The low-electron-count cationic platinum complex [Pt(ItBu')(ItBu)][BAr ], 1, interacts with primary and secondary silanes to form the corresponding σ-SiH complexes. According to DFT calculations, the most stable coordination mode is the uncommon η -SiH. The reaction of 1 with Et SiH leads to the X-ray structurally characterized 14-electron Pt species [Pt(SiEt H)(ItBu) ][BAr ], 2, which is stabilized by an agostic interaction. Complexes 1, 2, and the hydride [Pt(H)(ItBu) ][BAr ], 3, catalyze the hydrosilation of CO , leading to the exclusive formation of the corresponding silyl formates at room temperature.
