Heating a toluene solution of the bis(silyl)palladium complex [Pd(SiHPh2)2(dmpe)] (1) (dmpe = 1,2-bis(dimethylphosphino)ethane) at 60 C afforded a dipalladium complex with bridging silylene ligands, [{Pd(dmpe)}2(-SiPh2)2] (2), accompanied by H2SiPh2 elimination. An X-ray crystallographic study of 2 suggested the presence of a Si···Si interaction in the four-membered Pd2Si2 ring.
