addition-oxidative cyclization of nitriles with 2-aminopyridines or amidines was achieved in 1,2-dichlorobenzene or DMSO at 120–130 °C by using a 1,10-phenanthroline-functionalized MCM-41-supported copper(I) complex [Phen-MCM-41-CuBr] as the catalyst and air as the oxidant. The approach was used to generate a wide variety of 1,2,4-triazole derivatives in mostly high yields. This heterogeneous copper(I) catalyst

日期:——
efficient, and practical copper-catalyzed one-pot method for the synthesis of 1,2,4-triazoles has been developed via reactions of amidines. The procedure underwent sequential base-promoted intermolecular coupling (nucleophilic substitution) between two amidines and intramolecular aerobic oxidative dehydrogenation, and the inexpensive, convenient, and efficient method for the synthesis of 1,2,4-triazoles
