2,2?-Bipyridine-1,2-dithiolate mixed ligand complexes. Synthesis, characterisation and EPR spectroscopy

A series of new 2,2?-bipyridine/1,2-dithiolate transition metal complexes has been synthesised and characterised. As 1,2-dithiolate ligands 1,2-dithiooxalate (dto) and 1,2-dithiosquarate (dtsq) were used. It follows from the IR spectra that the multidentate dithiolate ligands coordinate exclusively via their sulfur atoms forming anMN2S2 coordination sphere. The central metal ions (M) are Cu2+, Ni2+, Pd 2+, Pt2+, and Zn2+. The complex Cu II(bpy)(dto)) could be studied by EPR spectroscopy and was measured as powder, diamagnetically diluted in the isostructural NiII(bpy) (dto)) host structure. The spin density contribution calculated from the experimental parameters is compared with the electronic situation in the frontier orbitals, namely in the semi-occupied SOMO of the copper complex, derived from quantum chemical calculations on different levels (EHT and DFT).

Pd complexes with trans-chelating ligands composed of two pyridyl groups and rigid pi-conjugated backbone

1,2-Bis(2-pyridylethynyl)benzene derivatives, having two pyridyl groups and pi-conjugated backbone, were prepared from the 1:2 Sonogashira reaction of 1,2-diiodobenzene with 2-alkynyl pyridines. The obtained ligands react with the palladium(II) complexes such as [PdCl2(cod)] and [PdCl 2(MeCN)2] to form the complexes with the ligands coordinated in a trans-chelating bidentate mode. The ligand obtained from 1,3-diiodobenzene and 2-alkynyl pyridine bridges two Pd(II) centers, yielding a dipalladium complex. A dichloropalladium complex with the trans-chelating ligand, containing two methoxy groups in the central arylene group, promotes coupling of phenyl lithium and of phenyl acetylene to yield the respective homo-coupling products. The ligand displacement reactions of {bis(2-pyridylethynyl)benzene}palladium(II) complex with phosphine and dinitrogen ligands, such as PPh3, dppe, dppb, en, tmeda, bpy and phen, takes place smoothly to release the trans-chelating ligand.

Palladium(II) Complex Formation with Germanium(II) and Tin(II) Compounds in Aqueous H3PO4

Complex formation is studied by means of optical, Moessbauer (119Sn), and IR spectroscopy. Formation of bimetallic complexes with the ratio Sn(Ge) : Pd ? 5 is found. The Pd-Sn compounds are characterized by the delta = 1.50-1.70 mm/s and the Delta = 1.90-2.20 mm/s. The charge transfer bands are observed at 220, 260, 290, and 360 nm for the Pd-Sn complexes and at 210 and 260 nm for the Pd-Ge complexes. The GePO4- ions are found to substitute completely for the SnPO4- ligands in the Pd-Sn complexes, which indicates that the Pd-Ge bonds are stronger. Possible coordination modes of the PO43- ions by the Ge(Sn) atoms are discussed within the terms of the v(P-O) vibrational frequencies.

Design, synthesis, and biological evaluation of a new palladium(II) complex: beta-lactoglobulin and K562 as targets

A water-soluble Pd(II) complex (2,2?-bipyridinglycinato Pd(II) nitrate) has been synthesized and characterized. The effect of synthesized complex on the carrier model protein structure and cell proliferation was investigated. Whey carrier protein beta-lactoglobulin-B (BLG-B) and chronic myelogenous leukemia cell line K562 were the targets. Fluorescence and CD instruments were used to assess effect of the complex on the protein structure at different temperatures. Growth inhibitory and apoptotic effect of the Pd(II) complex toward the cancer cells was measured using 3-(4,5-dimethylthiazol-2-yl)- 2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry. This complex exhibited potent cytotoxic properties against chronic myelogenous leukemia cell line K562. The cells showed different sensitivity to complex. Cytotoxic studies shown that Pd(II) complex induced apoptosis of K562 cells in a concentration and time dependent manner. Then, it might be concluded that Pd(II) complex is a promising antiproliferative agent and should execute its biological effects by inducing apoptosis. Results of fluorescence studies revealed that Pd(II) complex can quench the intrinsic fluorescence emission of the protein at different temperatures. The far- and near-UV CD studies displayed that the Pd(II) complex induces changes in the secondary and tertiary structures of BLG-B at different temperatures. The biological significance of this work is evident since BLG serves as a carrier molecule for several antitumor compounds. Therefore, the interaction of the Pd(II) complex (with antitumor activity) can provide useful information to better design metal anticancer complexes with fewer side effects.

Kinetics and mechanism of the interaction of thiosemicarbazide with di-mu-hydroxo bis(bipyridyl)dipalladium(II) ion

Kinetics of interaction between thiosemicarbazide with the title complex has been studied spectrophotometrically as a function of {Pd2(bipy)2(OH)22+], [thiosemicarbazide], pH and temperature. The reaction has been monitored at 280 nm, the lambdamax of the substituted complex, where the spectral difference between the reactant and the product is maximum. The reaction rate increases linearly with increase in [thiosemicarbazide]. The second order rate constants have been calculated from the slope of the kobs versus [ligand] plot. From the experimental findings an associative mechanism for the substitution process is suggested. The activation parameters (DeltaH = 50.4 ¡À 1.9 kJ mol-1, DeltaS = -105 ¡À 6 J K-1 mol-1) also support the proposition.

Multi-target heteroleptic palladium bisphosphonate complexes

Abstract: Bisphosphonates are the most commonly prescribed drugs for the treatment of osteoporosis and other bone illnesses. Some of them have also shown antiparasitic activity. In search of improving the pharmacological profile of commercial bisphosphonates, our group had previously developed first row transition metal complexes with N-containing bisphosphonates (NBPs). In this work, we extended our studies to heteroleptic palladium?NBP complexes including DNA intercalating polypyridyl co-ligands (NN) with the aim of obtaining potential multi-target species. Complexes of the formula [Pd(NBP)2(NN)]¡¤2NaCl¡¤xH2O with NBP = alendronate (ale) or pamidronate (pam) and NN = 1,10 phenanthroline (phen) or 2,2?-bipyridine (bpy) were synthesized and fully characterized. All the obtained compounds were much more active in vitro against T. cruzi (amastigote form) than the corresponding NBP ligands. In addition, complexes were nontoxic to mammalian cells up to 50?100 muM. Compounds with phen as ligand were 15 times more active than their bpy analogous. Related to the potential mechanism of action, all complexes were potent inhibitors of two parasitic enzymes of the isoprenoid biosynthetic pathway. No correlation between the anti-T. cruzi activity and the enzymatic inhibition results was observed. On the contrary, the high antiparasitic activity of phen-containing complexes could be related to their ability to interact with DNA in an intercalative-like mode. These rationally designed compounds are good candidates for further studies and good leaders for future drug developments. Graphic abstract: Four new palladium heteroleptic complexes with N-containing commercial bisphosphonates and DNA intercalating polypyridyl co-ligands were synthesized and fully characterized. All complexes displayed high anti-T. cruzi activity which could be related to the inhibition of the parasitic farnesyl diphosphate synthase enzyme but mainly to their ability to interact DNA.

Palladium/carbon catalyst regeneration and mechanical application method

A heterogeneous catalyst is a catalyst that is present in a different phase than the reactants. 14871-92-2. Such catalysts generally function by furnishing an active surface upon which a reaction can occur. 14871-92-2, name is (2,2¡ä-Bipyridine)dichloropalladium(II), introduce a new downstream synthesis route as follows.

General procedure: To a vigorously stirred solution of BzpheH2 (32.32 mg, 0.12 mmol) in 8 mL CH3OH/H2O (V:V 1:1), [Pd(bipy)Cl2] (20 mg, 0.06 mmol) was added. The mixture was heated to 50C and adjusted to pH 8-9 by NaOH solution, and then stirred for 2 h. The solution was concentrated to about 80% of the original volume. The complex I-a was separated from the solution after a few days.

Other significant industrial processes that involve the use of heterogeneous catalysts include the preparation of sulfuric acid, the preparation of ammonia, the oxidation of ammonia to nitric acid, and the synthesis of methanol.
