Large-scale preparation and labelling reactions of deuterated silanes
A catalytic synthesis of deuterated silanes SiEt3D, SiMe2PhD and SiPh2D2 is reported that allows their facile generation in a 3–4 g 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, which contain...

| Sumario: | A catalytic synthesis of deuterated silanes SiEt3D, SiMe2PhD and SiPh2D2 is reported that allows their facile generation in a 3–4 g 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, which contains a (η5‐C5Me5)Rh cation stabilized by coordination to a cyclometallated phoshine PMeXyl2 (Xyl = 2,6‐C6H3Me2). The same complex is also an active catalyst for the hydrosilylation of the CO and C≡N bonds of various ketones, aldehydes and α,β‐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. |
