Recyclable Perovskite As Heterogeneous Photocatalyst for Aminomethylation of Imidazo‐Fused Heterocycles

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 CsPbBr3 under the irradiation of visible light has been developed. This is the first example of CsPbBr3-catalyzed aminomethylation of imidazo-fused heterocycles. The eminent advantage of this work is in that, CsPbBr3 is easily prepared and can be used at least 5 times without obvious reduction in its activity, exhibiting high catalyst economic feature.
