Synthesis of a homoleptic tris(silylene)–palladium(0) complex and a silylyne-bridged tetranuclear palladium cluster

Abstract

We report the reactions of an iminophosphonamido-silylene (1) with different palladium complexes. The reaction of 1 with [Pd(PPh₃)₄] furnished a homoleptic tris(silylene)–palladium(0) complex. In contrast, treatment of 1 with [PdMe₂(tmeda)] led to the unprecedented formation of a non-planar μ³-silylyne-bridged tetranuclear palladium cluster that contains palladium atoms in different oxidation states.
