Abstract
An efficient and straightforward synthetic strategy has been established for the synthesis of biologically relevant thiophosphates. This method relies on visible light-induced oxidative dehydrogenative coupling between thiols and P(O)H compounds, utilizing lead-free Cs3Bi2Br9 perovskite as a heterogeneous photocatalyst with air serving as the oxidant. The reaction proceeds efficiently in 2-methyl tetrahydrofuran (2-MeTHF) under ambient temperature conditions, exhibits good tolerance towards a wide range of functional groups, and affords the target products in high yields. Furthermore, the photocatalyst can be readily recycled for at least 5 runs in gram-scale synthesis without a significant loss of catalytic activity.
