Visible-Light-Induced\nImine Hydrogenation Catalyzed\nby Thioxanthone-TfOH Complex

Amino compounds are important molecules, commonly found\nin nature\nand widely applied in industrial production. Recently, photocatalysis\nhas been discovered as an efficient method to synthesize amino compounds\nby promoting imine hydrogenation. In this work, a strategy of imine\nhydrogenation catalyzed by 2e<sup>–</sup> consecutive photoinduced\nelectron transfer (ConPET) process of thioxanthone-TfOH complex (9-HTXTF)\nwas thoroughly investigated with its reaction conditions optimized,\nsubstrate scope examined, and reaction mechanism elucidated, which\nprovides an efficient method for synthesizing amino compounds.
