[bmim]PF6/CuBr: a novel and recyclable catalytic system for the synthesis of propargyl amines

A novel and efficient method has been developed for the synthesis of propargyl amines in a one-pot operation from aldehydes, amines and alkynes by using copper( I) bromide immobilized in ionic liquids. The ionic liquid containing catalyst can be recovered and recycled in three to four subsequent run...

Summary:A novel and efficient method has been developed for the synthesis of propargyl amines in a one-pot operation from aldehydes, amines and alkynes by using copper( I) bromide immobilized in ionic liquids. The ionic liquid containing catalyst can be recovered and recycled in three to four subsequent runs with gradual decrease in activity.
