An environmentally friendly and resourceful modular protocol for the synthesis of phosphorochalcogenoates, phosphorochalcogenothioates, and phosphinothioates under blue light-emitting diode irradiation is described. The blue LED-promoted P–S, P–Se, and P–Te bond constructions occurred under metal-free, ligand-free, oxidant-free, and photocatalyst-free conditions with minimum chemical waste generation

A very simple N-chlorosuccinimide-promoted synthesis of thiophosphates through the coupling of thiols and phosphonates is reported. Notably, the reactions were carried out in the absence of a base. Functional groups including fluoro, bromo and trifluoromethyl are all tolerated by the reaction conditions employed. Both aryl and alkyl thiols are coupled smoothly with a broad spectrum of phosphonates to afford the corresponding thiophosphates in good to excellent yields.
