An efficient approach for the stereoselective synthesis of (E)-β-aminoacrylonitriles from 1,2,3-triazine is presented. The reactions employ Cu(OAc)2 to promote direct 1,2,3-triazine coupling with various secondary amines and subsequent aerobic oxidation without the participation of ligand, base or chemical oxidant additives. This user-friendly protocol has merits of substrate availability, easy operation
