Integrated electrochemical reactors in automated flow systems have been utilised for chalcogenophosphite formations. Multiple electrochemical reactions can be performed using a programmed sequence in a fully autonomous way. Differently functionalised chalcogenophosphites have been efficiently synthesised in short reaction times.

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
描述了一种在蓝色发光二极管照射下合成硫代磷酸酯、硫代磷酸酯和硫代磷酸酯的环保且资源丰富的模块化协议。蓝色 LED 促进的 P-S、P-Se 和 P-Te 键结构发生在无金属、无配体、无氧化剂和无光催化剂的条件下,化学废物产生最少,原子经济性高,提供了结果硫代磷酸酯、硫代硫代磷酸酯和硫代膦酸酯的产率从良好到优异。
absence of metal or any other additives, these transformations proceed through a spontaneous process at room temperature, which provide a convenient and compatible approach to a broad range of selenophosphates and thiophosphates.
