Highly active ruthenium(II) complex catalysts bearing an unsymmetrical NNN ligand in the (asymmetric) transfer hydrogenation of ketones

Exceptionally active ruthenium(II) complexes without an ancillary N-H functionality, but bearing a (chiral) unsymmetrical pyridyl-benzimidazolyl-based NNN ligand, exhibited very high catalytic activity in the (asymmetric) transfer hydrogenation ((A)TH) of ketones. The corresponding Ru-H complex, which is presumably the catalytically active species, was successfully isolated and structurally characterized by X-ray crystallography. Copyright

Mixed-matrix materials using metal-organic polyhedra with enhanced compatibility for membrane gas separation

Discrete metal-organic polyhedra (MOPs) containing copper(ii), palladium(ii), and iron(ii) nodes were synthesized as fillers for mixed-matrix materials (MMMs) with a polyvinylidine fluoride (PVDF) polymer phase and contrasted against an MMM containing a metal-organic framework, MOF-5. When a given MOP was soluble in the precursor solutions, the resulting MMMs were thin, flexible, and homogeneous based on microscopy and SEM imaging. Analogous MMM formation using either insoluble MOPs or the inherent insoluble MOF-5 showed a higher degree of phase separation and inhomogeneity. Even when a MOP was not fully soluble, a significant particle size decrease was observed in contrast to the MOF-5 materials wherein the crystallites remained largely intact. This is a consequence of solubilizing the MOP fillers into the polymer solvent. The crystallinity and thermal stabilities of the MMMs were compared to pure PVDF using powder X-ray diffraction, and differential scanning calorimetry, indicating that the incorporation of MOPs both decreased overall crystallinity as well as increased thermal stability. In addition, MMMs containing PdMOP and FeMOP showed improved gas permeabilities relative to pure PVDF for H2, N2, CH4, and CO2, with the 10 wt% FeMOP membrane more selective for CO2 over N2 and H2.

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.

Polymer supported palladium complex as a reusable catalyst for Suzuki coupling

Novel, simple and efficient catalytic system based on a polymer supported Pd complex of 2,6-bis(benzimidazolyl)pyridine, Pd(PS?BBP)Cl2, was found to be highly active for Suzuki?Miyaura cross-coupling of aryl halides with phenylboronic acids under mild conditions. The catalyst was characterized by CHN analyses, thermogravimetric analyses, BET surface area measurements, ICP-OES, FT-IR and electronic spectral studies. The effect of solvent, base, temperature and catalyst concentration on the coupling reaction of iodobenzene with phenylboronic acid was also investigated. A variety of functional groups are tolerated. The novel catalyst could be recovered in a facile manner from the reaction mixture and could be reused up to seven times without significant loss of catalytic activity.

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.
