Graphical Abstract
The more, the better: Treatment of [Pt(H)2(dcpe)] (dcpe=1,2-bis(dicyclohexylphosphino)ethane) with stoichiometric amounts of silane leads to the bis(silyl) complex [Pt{Si(OMe)3}2(dcpe)], whereas the use of an excess silane results in hydrodealkoxylations by repetitive SiO bond activation and the formation of SiH3 ligands (see scheme; Cy=cyclohexyl).

The structure was solved by direct methods and was refined with full-matrix least-squares methods on F 2 (SHELX-97).[27] Final R1, wR2 values on all data: 0.0277, 0.0351; R1, wR2 values for 8975 reflections with I0>2σ(I0): 0.0171, 0.0343; residual electron density +0.654/−0.986 e Å3. Hydrogen atoms were placed at calculated positions and refined using a riding model. The hydrogen atoms on the silicon were located on the difference Fourier map and refined isotropically.
