phosphine-stabilized platinum species has been reported that reacts intermolecularly with unactivated C-H bonds, although intramolecular reaction is facile. Here, the report that thermal reductive elimination of neopentane from cis-hydrido-neopentyl(bis(dicyclohexylphosphino)ethane)platinum(II) (1) produces the reactive intermediate (bis(dicyclohexylphosphino)-ethane)platinum(0) (2) and that 2 reacts with C-H

The photochemistry of the diphosphino Pt(II) hydrides [LPtH2] (L = t-BU)(2)P(CH2),P(t-Bu)(2) (7): L = (t-Bu)(2)P(CH2)(3)P(t-Bu)(2) (8),L = (t-Bu)(Ph)P(CH2)(2)P(Ph)(t-Bu) (9)) is reported. The primary photoevent is the dissociation of H-2 and formation of the 14-e [LPt] species. These coordinatively unsaturated intermediates provide a versatile entry point into the C-H bond activation of hydrocarbons. [LPt] reacts with benzene in an oxidative addition reaction to yield [LPt(H)(C6H5)] complexes. The importance of the metal centre and ancillary ligation in the C-H bond activation is discussed.
