Abstract
A three-component coupling of aldehydes, amines and an alkyne to generate propargylic amines in nearly quantitative yields, using a layered double hydroxide-supported gold (LDH-AuCl4 ) catalyst is described. Both aromatic and aliphatic aldehydes and amines are used for the reaction. No additional co-catalyst or activator is required.
Key word
layered double hydroxides - gold - coupling reaction - propargylic amines - heterogeneous catalysis
