Synthesis and properties of a methyl derivative of zeise's dimer

Abstract

A methyl(ethylene)platinum(II) complex [Pt₂(µ-Cl)₂Me₂(C₂H₄)₂] has been prepared and characterized; it forms complexes [PtClMe(C₂H₄)L] where L = pyridine, Me₂S, or C₂H₄, undergoes exchange with unsaturated reagents (un) where (un)= PhCHCHPh, CH(CO₂Me)CH(CO₂Me), or PhCCPh to give [Pt₂(µ-Cl)₂Me₂(un)₂], undergoes insertion with CF₃CCCF₃ to give, after treatment with pyridine, [PtCl{C(CF₃)C(CF₃)Me}(py)₂], and reacts with Zeise;s dimer to give the unsymmetrical dimer [Pt₂(µ-Cl)₂ClMe(C₂H₄)₂].
