摘要：

[HC(PY)3W(NO)2(CO)](SbF6)2 is a feasible Lewis acid catalyst precursor for the addition of silylated C-nucleophiles to carbonyl compounds. The O-silylated adducts are easily isolated without aqueous wort-up and the catalyst can be recycled. A remarkable solvent effect is found in the addition of TMS-CN to cyclohexanones.
