Seven carbonyl compounds were thionated with phosphorus pentasulfide promoted by microwave irradiation under solvent-free conditions. The thiocarbonyl compounds were synthesized in 76%~93% yields. The optimized reaction conditions:the molar ratio of substrates and PP2S5 is 4:1,temperature is 100℃ and time is 15~20 min. The structures of products were characterized by 1H NMR and 13C NMR.
