摘要
An efficient and eco-friendly carbon nitride nanosheet(NM-g-C3N4)-catalyzed decarboxylative coupling reaction of imidazo-fused heterocycles(i.e.,imidazo[1,2-a]pyridines,benzo[d]imidazo[2,1-b]thiazole)with N-phenylglycines in dimethyl carbonate(DMC)has been developed.The toxic solvents,external oxidants,and restricted reaction conditions could be effectively avoided in this powerful and sustainable protocol.Remarkably,NM-g-C3N4 could be straightforwardly recovered by simple centrifugation and recycled and reused at least 7 times without an obvious decrease in catalytic activity.
