A novel dinuclear palladium complex with one bridging dialkylsilylene ligand 6 was synthesized by the reaction of isolable dialkylsilylene 7 (R2Si:) with two equiv of bis(tricyclohexyl)phosphinepalladium (8). Complex 6 as a prototypical dipallada-silacyclopropane reacts with molecular hydrogen to give dihydrosilane 10 (R2SiH2) together with 8 and metallic palladium.
