Abstract
The oxidation process is widely explored and used to synthesize diverse organic chemicals. Herein, a unified metal-free photooxidative platform for the cleavage of C-heteroatom bonds has been developed. In these reactions, the aminoquinolate diarylboron (AQDAB) complex is utilized as the photocatalyst, instigating the oxidation process induced by visible light. The cleavage of C-heteroatom bonds can be achieved chemoselectively, affording the formal carbonylation product of C-N, C-S, and C-Se bonds. This method provides a channel for connecting amines, thiols, or selenides with the carbonyl compounds directly, broadening the potential applications of oxidation as a synthetic tool.

Abstract
The reduction of mercaptans plays an important role in diverse areas such as protein synthesis, polymer science, environmental study, and pharmaceutical chemistry. Despite significant advancements in this area, particularly in light-induced transformations, review articles have rarely been reported on this topic. Thus, this review article emphasizes the direct photoinduced desulfurization and functionalization of thiols to alkanes or coupling products, with a focus on significant advancements made in the last decade. The progress is discussed according to the types of bonds formed from the cleavage of Csp3-SH bonds.
