SiX3-SiXiMe3−i (i = 0, 1, 2; X = Cl, Br), trisilanes SiX2(SiXiMe3−i) (i = 0, 1) and branched tetrasilanes SiX(SiXMe2)3 were synthesized and their behavior towards the Lewis-base catalyzed hydrogenation by stannanes was investigated. In the case of methylchlorodisilanes SiCl3-SiCliMe3−i Si-Si bond cleavage competes with the hydrogenation reaction.
