Using a readily accessible and high-efficiency photocatalyst for inducing chem. transformations is highly desirable. All inorganic lead halide perovskites (APbX3, X = Cl, Br, I) are utilized intensively in photovoltaics providing outstanding optoelectronic performance and are easy-to-process, but their use in organic synthesis is still in its infancy. Herein, a facile protocol for the photocatalytic oxidation of a series of amines and sulfides to their corresponding imines and sulfoxides with excellent yields and selectivity using CsPbBr3 as a visible-light catalyst is reported. The result show that amines bearing electron-donating groups give rise to aldehydes as the final products, while amines with electron-withdrawing groups afford imines as the major products. Reaction mechanism studies reveal that the photogenerated holes (h+), superoxide radicals (O2 ̇-) and singlet oxygen are involved in the reaction performed in air and O2 atmospheres. In addition, for the reaction conducted under anaerobic conditions, free radicals generated by amines plays a vital role in determining the transformation of amines to imines.
