Abstract: 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 P2S5 is 4∶1, temperature is 100 ℃ and time is 15~20 min. The structures of products were characterized by 1H NMR and 13C NMR.

Key words: microwave-irradiation, solvent-free, thiocarbonyl reaction, phosphorus pentasulfide
