Addition of triphenylsilane, trimethylsilane, or triethylsilane to [Cp*(PMe3)Rh(Me)(CH2-Cl2)] BAr′4 (4), a cationic Rh(III) complex, resulted in Si-H bond activation and release of methane below -80°C. The rare, nonclassical silane complexes [Cp*(PMe3)Rh((C6H4) (η2-HSiPh2))]BAr′4 (6), [Cp*(PMe3)Rh(SiMe3)(η2- HSiMe3)]BAr′4 (9), and [Cp*(PMe3) Rh(SiEt3)-(η2-HSiEt3)] BAr′4 (11) have been generated and characterized by NMR spectroscopy. Of note was the presence of 29Si satellites of the hydride resonances of each of these compounds and large 1JSi-H coupling constants (56-84 Hz), diagnostic of the presence of η2-silane ligands.
