Abstract
Abstract Reaction of iodotrimethylplatinum(IV) tetramer with bis(1,3-diphenyl-2-imidazolidinylidene) [(Hdpim) 2 ] gave a new dinuclear carbene complex, [{Pt(dpim)I} 2 ](dpim 1,3-diphenyl-2-imidazolidinylidenato-2- C ,2′- C ), III, in 84% yield, which contains a cycloplatinated carbene structure. Some mononuclear derivatives, [Pt(dpim)(acac)], [Pt(dpim)I{P(OCHMe 2 ) 3 }], [Pt(dpim)-(NCCH 3 ) 2 ]ClO 4 , and [Pt(dpim)(COD)]ClO 4 were prepared from III and characterized by means of elemental analysis, IR and NMR spectroscopy, and molar conductivity. An intermediate species, [{PtMeI(Hdpim)} 2 ], leading to III is discussed also.
