The Reformatsky reaction of bromodifluoromethyl ketones and imines took place readily in the presence of Zn/CuCl at room temperature to afford β-amino α,α-difluoro ketones in good yields. Using (S)-tert-butanesulfinyl as a chiral auxiliary, the asymmetric Reformatsky reaction was also achieved and found to proceed with excellent diastereoselectivities. A plausible model is proposed to account for the
