摘要：

Protonolysis of the complexes trans-[Pt(PEt3)2(R)(Me)] (R = C6H5 ; m-MeC6H4 ; o-MeC6H4 ; m-FC6H4 ; p-FC6H4 ; m-CF3C6H4 and C6F5) by hydrogen chloride in methanol/water ( 90 10 v/v) selectively cleaves the alkyl group yielding trans-[Pt(PEt3)2(R)Cl] and methane. A kinetic study of these reactions suggests that the primary step involves a proton transfer to the carbonmetal σ-bond with release of CH4 in a three-center transition state. © 1979.
