The 1:1 complexes formed in situ from nickel(II) acetate and the thiosemicarbazones of ortho-hydroxy aromatic aldehydes catalyze the hydrosilylation of imines. A variety of imines were reduced in good to excellent yields employing two equivalents of a silane such as triethylsilane and 5 mol% of the catalysts.
