The addition of alkylzinc halides to imines has been studied under different conditions. Whereas Mannich-type reactions with sulfonyl imines occurs upon simple heating, the use N-alkyl imines required an additional activation: the use of acetyl chloride led to the preparation of N-acyl tertiary amines whereas trimethylsilyl chloride afforded a direct access to unprotected secondary amines.
