Activation of Si-Si and Si-H bonds at Pt: a catalytic hydrogenolysis of silicon-silicon bonds
DOI: 10.1039/C3DT32530J, PaperJan Voigt, Maren A. Chilleck, Thomas Braun
A reaction of Ph2HSiSiHPh2 with H2 in the presence of catalytic amounts of cis-[Pt(SiPh2H)2(PEt3)2] and trans-[Pt(SiPh2H)2(PEt3)2] yielded H2SiPh2. The catalytic hydrogenolysis of Me3SiSiMe3 in the presence of [Pt(PEt3)3] is much slower and needs a higher temperature to proceed.
