Phosphinosilylenes as a novel ligand system for heterobimetallic complexes

A dihydrophosphinosilylene iron complex [LSi{Fe(CO)4}PH2] has been prepared and utilized in the synthesis of novel heterobimetallic complexes. The phosphine moiety in this phosphinosilylene complex allows coordination towards tungsten leading to the iron-tungsten heterobimetallic complex [LSi{Fe(CO)4}PH2{W(CO)5}]. In contrast, the reaction of [LSi{Fe(CO)4}PH2] with ethylenebis(triphenylphosphine)platinum(0) results in the formation of the iron-platinum heterobimetallic complex [LSi{Fe(CO)4}PH{PtH(PPh3)2}] via oxidative addition.     «
