Abstract: cis-Wydridoneopentyl [bis (dicyclohexylphosphino) ethane] platinum (II)(1) reductively eliminates neopentane and generates [bis (dicyclohexylphosphino) ethane] platinum (0)(2). This bent bis (phosphine) platinum (O) complex was not observed directly; its intermediacy was inferred from the presence of this moiety in the reaction products. The intermediate 2 reacts with alkyl,(trimethylsilyl) methyl, aryl, and benzyl carbon-hydrogen ...
