ResumenA catalytic synthesis of the deuterated silanes SiEt3D, SiMe2PhD and SiPh2D2, is reported that allows their facile generation in a 3-4 gram scale, utilizing D2 (0.5 bar) as the hydrogen isotope source and low catalyst loadings (0.01 mol %). The catalyst precursor is the rhodium (III) complex 1, that contains a (η5-C5Me5)Rh cation stabilised by coordination to a cyclometallated phoshine PMeXyl2 (Xyl = 2,6-C6H3Me2). The same complex is also an active catalyst for the hydrosilylation of the C=O and CN bonds of various ketones, aldehydes and ,-unsaturated nitriles. Hence, combination of these two properties permits development of a simple and proficient one-flask, two-step procedure, for the deuterosilylation of these substrates
