A series of Mn(i) photo-activated carbon monoxide-releasing molecules with benzimidazole coligands: Synthesis, structural characterization, CO releasing properties and biological activity evaluation

Five Mn(i) photo-activated carbon monoxide-releasing molecules (photo-CORMs) with benzimidazole coligands, namely [MnBr(CO)3L1] (1, L1 = 2-(2-pyridyl)benzimidazole), [Mn(CO)2L1(PPh3)2](ClO4) (2), [MnBr(CO)3L2] (3, L2 = 2,2?-bisbenzimidazole), [MnBr(CO)3L3]¡¤CH3OH (4, L3 = 2,6-bis(benzimidazole-2?-yl)pyridine) and fac-[MnBr(CO)3L4] (5, L4 = 2,4-bis(benzimidazole-2?-yl) pyridine) were synthesized by reactions of MnBr(CO)5 with complexes L1-L4, respectively, and characterized via single crystal X-ray diffraction, elemental analysis, 1H-NMR, 13C-NMR, IR, UV-vis and fluorescence spectroscopy. The CO-release properties of 1-5 were investigated using the myoglobin assay and CO detection, and the results show that all of the complexes could release CO rapidly upon exposure to 365 nm UV light. Comparing their half-lives of CO release, we found that increasing the degree of unsaturation and conjugation of the ligand frame could be advantageous for prolonging the time of CO-release, and that the luminescence intensity of 1-5 could gradually be enhanced. The cellular fluorescence imaging tests demonstrate that these Mn(i) photo-CORMs can be taken up by human liver cells (HL-7702) and liver cancer cells (SK-Hep1), and exhibit good capabilities for bioimaging. A cell viability assay for SK-Hep1 shows that the anticancer activity of 3 is better than that of other complexes.

(2,4,6-tris(trifluoromethyl)phenyl)palladium(II) complexes

Complexes containing one or two Fmes ligands (Fmes = 2,4,6-tris(trifluoromethyl)phenyl = nonafluoromesityl) either trans or cis are obtained by treating palladium(II) chloro complexes with Li(Fmes): trans-[PdCl2L2] (L = tetrahydrothiophene (tht), PPh3) lead to trans[Pd(Fmes)ClL2] (L = tht, PPh3) or trans-[Pd(Fmes)2L2] (L = tht); [PdCl2(L-L)] (L-L = 1,5-cyclooctadiene, 2,2?-bipyridine) give [Pd(Fmes)Cl(L-L)} (L-L = COD, bipy) or [Pd(Fmes)2-(bipy)]. The structures of two complexes containing two Fmes ligands in trans and cis arrangement, trans-[Pd(Fmes)2(tht)2] (2) and [Pd(Fmes)2(bipy)] (6), respectively, have been determined by X-ray diffraction. In spite of the severe steric congestion the complexes are four coordinated. Distortions due to the bulkiness of the ortho substituents and short Pd…F3C-ortho distances are observed. The high degree of steric crowding is also responsible for slow rotation around the Pd-P bonds in the complex trans-[Pd(Fmes)Cl(PPh3)2]. DeltaG? associated with this motion is 12.8 kcal mol-1, one of the highest values reported so far for rotation around M-PPh3 bonds. Complexes 2 and 6 are redox inactive by cyclic voltammetry in the range -1.8 to +1.8 V.

Water-promoted palladium catalysts for methane oxidation

A water-tolerant, active and high-selective palladium catalyst, (2,2?-bipyridine) dichloropalladium(II) is proposed for the oxidation of methane to a methanol derivative with molecular oxygen as the oxidant at temperatures below 120 C, and its activity can be increased by three times at 100 C when the volume ratio of water to CF3COOH solvent is 1:5. In addition, the addition of perfluorooctane can enhance the yield of methanol further.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: catalyst-palladium, you can also check out more blogs about14871-92-2

Self-assembly of dinuclear helical and nonhelical complexes with copper(I)

The ligand 1,3-bis(1-methylbenzimidazol-2-yl)benzene (mbzimbe, L3) reacts with copper(I) to give [Cu2(L3)2](ClO4)2. The crystal structure of this compound (Cu2C44H36N8Cl2O 8, a = 13.661 (1) A, b = 19.829 (3) A, c = 15.413 (2) A, orthorhombic, Pbca, Z = 4) shows a dinuclear centrosymmetrical nonhelical structure in which each copper is linearly coordinated by a benzimidazole group of each ligand. The complex displays a weak intramolecular stacking interaction between the benzene groups. This complex can be considered as a stereoconformer of the double-helical complex [Cu2(L1)2](ClO4)2 (L1; 2,6-bis(1-methylbenzimidazol-2-yl)pyridine). Conductivity measurements and UV-visible spectra show that the dimeric structures are maintained in solution in polar aprotic solvents. 1H NMR measurements show that [Cu2(L1)2]2+ retains its helical structure in solution. Comparison of helical and nonhelical structures with those formed by Cu(I) with related ligands allows discussion of the factors favoring the formation of self-assembled dinuclear complexes.

Di- and tripalladium(II) and -platinum(II) complexes containing 7-amino- 1,8-naphthyridin-2-one as a bridging ligand – Oxidation of a [Pt3]6+ core to [Pt3]8+

All three dinuclear complexes [Pd2(donp)2(bpy)2] (1) (H2donp = 1,8- naphthyridin-2,7-dione), [Pd2(H2nonp)2(bpy)2](ClO4)2 (2), and [Pt2(H2nonp)2(bpy)2](PF6)2 (3) (H3nonp = 7-amino-1,8-naphthyridin-2- one) exhibit the mu-1kappaN1:2kappaN8 bridging mode for their head/tail orientated naphthyridine ligands. Whereas 1 and 3 may be prepared by direct reaction of the dinucleating ligand with [MCl2(bpy)], formation of competing tripalladium(II) complexes must be avoided for 2 by employment of the precursor H2acnonp (7-acetamido-1,8-naphthyridin-2-one), which affords [H2nonp]- on cleavage of its original acetyl group. A mixture of the head/tail (4a) and head/head (4b) isomers of [Pd3(Hnonp)2(bpy)3](ClO4)2 is obtained when H3nonp is treated with [PdCl2(bpy)] and LiOH at room temperature for 2 d, followed by precipitation with LiClO4. Contrastingly exclusive formation of 4a is observed upon refluxing this reaction mixture for 3 d in aqueous solution. The [Hnonp]2- ligands exhibit a mu3- 1kappaN1:2kappaN8:3kappaN7 bridging mode that leads to short Pd ¡¤¡¤¡¤ Pd interactions of 2.781(2) and 2.775(2) A. Similar metal-metal distances of 2.771(3) and 2.816(3) A are observed in head/head- [Pt3(acnonp)(Hnonp)(bpy)3]Cl2 (5). An in situ 2e–oxidation (Ag+/Ag) of the [Pt3]6+ core in triplatinum(II) species such as 5 formed by the reaction of [PtCl2(bpy)] with H2acnonp allows the isolation of diamagnetic dark-brown head/head-[Pt3(Hnonp)2(NO3)(bpy)3](ClO4)2 (NO3) (6) with an average oxidation state of Pt (2.67+). The Pt-Pt distances of 2.723(2) and 2.670(2) A are markedly shorter than in 5.

Molecular design of supramolecular polymers with chelated units and their application as functional materials

This article summarizes the basic concepts and synthetic strategies leading to various types of supramolecular polymers with chelated units, including linear, branched, cross-linked, and heterometallic polymers. Particular attention is paid to such new synthetic approaches to supramolecular polymers as hierarchical and orthogonal self-assembly based on a combination of metal?ligand interaction with hydrogen bonds and host?guest interactions. Metallosupramolecular polyelectrolytes, supramolecular polymer gels, self-assembled metallosupramolecular monolayers, and supramolecular metal chelate dendrimers are analyzed. The stimuli-responsive, self-healing, and shape memory supramolecular polymers with chelated units are considered. The bibliography includes articles published over the past five years.

Metal-Purine Interactions: Homo- And Heterodinuclear Platinum(II) and/or Palladium(II) Complexes of 8-Thiotheophylline. Crystal Structures of [Pt(mu-TT)(dppm)]2¡¤2DMSO and [(dppm)Pt(mu-TT)2Pd(dppm)]¡¤7H2O

The reaction of cis-[MCl2(dppm)] (M = Pt(II) and Pd(II); dppm = bis(diphenylphosphino)methane) with H2TT and NaOH (H2TT = 8-thiotheophylline) yields neutral mononuclear [M(HTT-S(8))2(dppm)] complexes. Homodinuclear [M(mu-TT-N(7),S(8))(dppm)]2 (M = Pt(II) and Pd(II)) are prepared either by the reaction of [M(HTT)2(dppm)] with cis-[MCl2(dppm)] and NaOH or by the direct reaction of cis-[MCl2(dppm)] with Na2TT, prepared in situ from H2TT and NaOH. The crystal structure of the Pt derivative is reported: [Pt(mu-TT)(dppm)]2¡¤-2DMSO (3) crystallizes in the triclinic space group P1 with a = 12.949(3) A, b = 13.009(3) A, c = 22.980(5) A, alpha = 96.89(3), beta= 103.53(3), gamma = 106.43(3), Z = 2, and R1 = 0.045. Heterodinuclear [(dppm)Pt(mu-TT)2-Pd(L-L)] complexes are obtained by reaction of [Pt(HTT)2(dppm)] with [PdCl2(L-L)] in basic medium (L-L = dppm and 2,2?-bipyridine). The crystal structure of [(dppm)Pt(mu-TT)2Pd(dppm)]¡¤7H2O (5) is reported. The complex crystallizes in the orthorhombic space group P212121] with a = 16.560(5) A, b = 17.063(5) A, c = 24.428(5) A, Z = 4, and R1 = 0.042. The structures of 3 and 5 are almost identical, by which 5 can be seen as an isomorphic substitution of one of the Pt(II) ions of 3 by a Pd(II) ion. The structures consist of dinuclear units having a pseudo-2-fold axis perpendicular to that defined by the metal atoms. The two metal atoms are bibridged by two mu-TT-N(7),S(8) ligands, in a head to tail arrangement. The square-planar coordination of the metal atoms is completed by a chelate dppm ligand. The steric repulsions between the bulky dppm ligands must be the main factor precluding metal-metal interaction in these compounds.

Enhanced biomimetic CO2 sequestration and CaCO3 crystallization using complex encapsulated metal organic framework

A new biomimetic complex (Co-BBP) that mimics the active site of carbonic anhydrase (CA) was prepared by the coordination of cobalt (II) with 2, 6-bis(2-benzimidazolyl) and was encapsulated into a metal organic framework (Co-BBP@Tb-MOF). Carbon dioxide (CO2) sequestration was carried out via an in vitro mineralization approach using these biomimetic catalysts. The biomimetic catalysts were expected to enhance CO2 hydration and calcium carbonate (CaCO3) crystallization based on the same mechanism as that of CA.

Selective carbonylation routes to thiocarbamates. An alternative to phosgene

A new route for the synthesis of thiocarbamates using a transition metal complex and CO as a replacement for phosgene has been discovered. The complex (PPh3)2PdCl2 reacts with N-benzylmethylamine, 4-chlorobenzenethiol, and CO to selectively generate a thiocarbamate. Kinetic studies and the isolation of several intermediates in this reaction allow for the proposal of a mechanistic scheme.

Syntheses of palladated aryldithioacetals. Unexpected rearrangement involving C-S and C-Pd bonds

The reaction of C6HI(OMe)3-2,3,4- CH(STo)2-6 (1) (To = 4-tolyl) with [Pd(dba)2] (dba = dibezylideneacetone) at room temperature gives [Pd2{kappa2-C,S-CH(STo)(C6H(STo-2) (OMe)3-3,4,5)2 (mu-I)2] (3) or, in the presence of Tl(OTf) (OTf = CF3SO3) and bpy (2,2?-bipyridine), the cationic cyclopalladated complex [Pd{kappa2-C,S-C6H(OMe)3-2,3,4- CH(STo)2-6}(bpy)]OTf (2). 3 reacts with Tl(OTf) and (i) RNC (1:2:4) to give cis-[Pd{kappa2-C,S-CH(STo){C6H(STo-2) (OMe)3-3,4,5}}-CNR)2]OTf [R = 2,6-dimethylphenyl (4), tBu (4?)] or (ii) bpy to give an isometric form of 2, cis-[Pd{kappa2-C,S-CH(STo){C6H(STo-2)(OMe)3- 3,4,5}}(bpy)]OTf (5). The last reaction can be reversed by reacting 5 with NaI. The compound 2 reacts with NaI to give [Pd(C6H(OMe)3- 2,3,4-(CH(STo)2-6)I(bpy)] (6), which can be also prepared by reaction of 1 with [Pd(dba)2] in the presence of bpy. Complex 2 isomerizes to 5 when refluxed in 1,2-dichloroethane. The crystal structures of 2 and 4 have been determined by X-ray diffraction studies.
