Selective formation of bimetallic group 10 complexes using the Cs symmetric, bicyclic diphosphane P2C12H20 is reported herein. With its eclipsed lone pairs disposed at a relative angle of ca. 45 , the diphosphane framework is ideally suited to form multiple bridges between two metal centers. The complexes contain {M2P6} cages with three diphosphane bridges and a pair of trans-axial ligands such...

Reductive elimination of carbon-carbon bonds occurs in numerous metal-catalysed reactions. This process is well documented for a variety of transition metal complexes. However, carbon-carbon bond reductive elimination from a limited number of Au(III) complexes has been shown to be a slow and prohibitive process that generally requires elevated temperatures. Herein we show that oxidation of a se...

Comparative reactivities of three diaqua(tetraamine)Co(III) complexes towards hydrolysis of 4-nitrophenyl phosphate was undertaken. The results were contrasted with prussian blue promoted hydrolysis of 4-nitrophenyl phosphate. The tetraamineCobalt(III) complexes accelerated the hydrolytic reaction to varying degrees with the following reactivity order. [(tn)2Co(OH2)2] < [(trpn)Co(OH2)2] < [(tme...

Isomerization of linear alkanes has had considerable importance for the refining industry because the isomers formed in this reaction have high octane number. Most works reported in the literature studied the use of bifunctional catalysts, i.e., ones that have acid sites and metallic sites. In this study, bifunctional monometallic (Ni or Pt) and bimetallic catalysts (Pt-Ni), using HUSY zeolite ...

Since the discovery of their extraordinary reactivity in hydrolytic kinetic resolution terminal epoxides about twenty years ago, chiral cobalt-salen complexes have been shown to be essential for many other asymmetric catalytic reactions. This account summarizes inspiring works dedicated new and mode action, as well processes towards optimization cooperativity bimetallic activation implementatio...

Bioactive 1,1'-(4,4'-di-ferrocenyl)di-phenyl thiourea and various metal complexes of this ligand have been successfully synthesized and characterized by using physicoanalytical techniques such as FT-IR and multinuclear ((1)H and (13)C) NMR spectroscopy along with melting point and elemental analyses. The interaction of the synthesized compounds with DNA has been investigated by using cyclic vol...

A modification of the previously developed synthetic approach towards dinuclear flexibly linked salphen complexes is successfully utilized for the preparation of heterodinuclear salphen dimers. A dinuclear salphen species with Pd(II) and Cr(III) centers bears a stronger structural resemblance to the related bis-Cr(III) compound than the corresponding mononuclear Cr(III) salphen complex. Therefo...

In 2009, we reported C-halogen reductive elimination reactions from dinuclear Pd(III) complexes and implicated dinuclear intermediates in Pd(OAc)(2)-catalyzed C-H oxidation chemistry. Herein, we report results of a thorough experimental and theoretical investigation of the mechanism of reductive elimination from such dinuclear Pd(III) complexes, which establish the role of each metal during red...
