Triethylamine solubilised phosphorous pentasulphide (P4S10) has been evolved as the thiation agent in heterocycles such as substituted benzoxazin-4-ones, 2-pyrazolin-4-ones and pyrimidine-2,5-dione derivatives. The simple and convenient operation involving stirring (24 h) of the reaction mixture at room temperature results in the isolation of the desired products in quantitative yield.
