Abstract

Abstract: Reductive elimination of neopentane from cis-[bis (dicyclohexylphosphino) ethane] hydridoneopentylplatinum (11)(1) generates the reactive intermediate [bis ( dicyclohexylphosphino) ethane] platinum (O)(2), which forms cis-[bis ( dicyclohexylphosphino) ethane] hydridophenylplatinum (I1)(3) upon reaction with benzene. The rate-determining step is reductive elimination of neopentane: E,= 28.0 (0.4) kcal/mol, ...
