Efficient hydrosilylation of imines using catalysts based on iridium(<scp>iii</scp>) metallacycles

Abstract

Ir(<bold>iii</bold>) metallacycles were applied as catalysts for the hydrosilylation of ketimines and aldimines by using sodium tetrakis[(3,5-trifluoromethyl)phenyl]borate, NaBArF₂₄, as an additive. By using a slight excess of the organosilane reagent, the reactions proceeded rapidly and efficiently, at low catalyst loadings and at room temperature.
