Abstract
Abstract A sustainable and cost‐effective protocol for direct aminomethylation of imidazo‐fused heterocycles by decarboxylative coupling reaction of N ‐phenylglycines with imidazo‐fused heterocycles in the presence of CsPbBr 3 under the irradiation of visible light has been developed. This is the first example of CsPbBr 3 ‐catalyzed aminomethylation of imidazo‐fused heterocycles. The eminent advantage of this work is in that, CsPbBr 3 is easily prepared and can be used at least 5 times without obvious reduction in its activity, exhibiting high catalyst economic feature. magnified image
