Description
Summary:A simple and efficient Cu(OAc)2.H2O-catalyzed aerobic oxidation of amidines with nitriles for the synthesis of multi-substituted 1,2,4-triazoles has been achieved. The procedure constructs multi-substituted 1,2,4-triazoles and has the advantages of operational simplicity, broad substrate scope, and no need for prefunctionalized reagents. A possible mechanism has been proposed via the cascade N-H functionalization and N-N/C-N bond formation.
