Tetrabenzylhafnium has been explored as a new organometallicreagent for the imine addition reaction. This reagent tolerates a wide scope of imines, affording α-branched amines in excellent yields without the use of any additive or catalyst. This new reagent shows higher efficiency than that observed for classic Grignard and organolithium reagents.
