A novel, simple and convenient thionation protocol for carbonyl compounds with the system PSCl3/H2O/Et3N allows a clean, rapid, and efficient synthesis of a variety of thiocarbonyl compounds such as thioamides, thiolactams, thioketones, thioxanthones and thioacridone under solventless condition with microwave irradiation.
