Abstract

An efficient and practical method for the one-pot Mannich reaction of aromatic ketones with aldehydes and amines at room temperature has been developed under solvent-free conditions catalyzed by (C4H12N2)2[BiCl6]Cl·H2O (3 mol%). The catalyst may also be recycled multiple times by simple isolation protocols without compromising the catalytic efficiency.
