Abstract

The coupling of an aldehyde, an amine, and an alkyne to yield propargyl amines was performed in a deep-eutectic solvent composed of zinc chloride and dimethylurea. The deep-eutectic solvent acts simultaneously as catalyst and solvent giving access to a variety of propargyl amines, which were isolated in moderate to very good yields.
