Diplatinum complexes with two µ-HSiEt2 groups undergo exchange of the bridging silyl ligands with secondary silanes with phenyl substituents. Equimolar reactions of H2SiPh2 produce new diplatinum complexes with µ-SiPh2 and µ-H2SiEt2 groups and with µ-HSiPh2 and µ-HSiEt2 groups. Coordination of bidentate phosphine ligands to the Pt centers facilitates the Si−H bond activation and elimination of H2 to form silylene-bridged dinuclear complexes.
