Electron transfer reactions involving trans- and fluorinated benzonitriles

, p. 225 - 234 (1992)
The complex trans- reacts with activated benzonitriles such as 4-R-C6F4CN (R=F, H, CN, OCH3) bearing electron-withdrawing substituents to give the new platinum(II) aryl complexes trans-(PCy3)2>, which have been isolated and fully characterized, and a hydridofluoride trans-, where F is either F or HF2, which has been detected in solution.These complexes and related by-products from the reaction have been characterized by one- and two-dimensional multinuclear NMR spectroscopy.A reaction mechanism involving rate-determining electron transfer from the dihydride complex to the organic substrate is postulated on the basis of (i) the relative reaction rates for the nitriles (p-C6F4(CN)2 > C6F5CN > p-C6HF4CN > p-C6F4(OCH3)CN > o,o-C6H3F2CN), which parallel their electron affinities, and (ii) the observation of a radical by ESR spectroscopy after spin-trapping with PBN.
Unprecedented Borane, Diborane(3), Diborene, and Borylene Ligands via Pt-Mediated Borane Dehydrogenation
Arnold, Nicole,Braunschweig, Holger,Dewhurst, Rian D.,Ewing, William C.
, p. 76 - 79 (2016)
Reactions of an aryldihydroborane with a Pt0 complex lead to a range of novel products, including complexes with bridging diborene and diborane(3) ligands and a complex with both borylene and borane (M → B) ligands. The products imply varying d

A series of platinum metal silyl hydride complexes were prepared in solution by reaction of Pt(PCy3)2 with the appropriate silane, HSiR2R′. The complex was characterized using x ray crystallography at -100°C. The platinum center was found to exhibit a distorted-square-planar geometry with angles P(1)-Pt-P(2)=113.55(3)°, P(1)-Pt-Si=146.83(3)°, and P(2)-Pt-Si=99.37(3)°. The reaction of Pt(PCy3)2 with chlorinated hydrosilanes at -78°C was also found to yield analogues complexes which isomerized to their trans isomers on warming at room temperatures.
MIXED LIGAND COMPLEXES OF PLATINUM(0) CONTAINING DIPHOSPHINES
Clark, Howard C.,Kapoor, Pramesh N.,McMahon, Ian J.
, p. 107 - 116 (2007/10/02)
The reaction of PtCl2L (L = diphosphine) with the appropriate diphosphine L' in ethanol followed by reduction with aqueous sodium borohydride leads to either disproportionation to give mixtures of the bis(diphosphine) complexes PtL2 and PtL'2 or to the fo
