A convenient and efficient protocol for the thiolysis of oxiranes using2-[bis(alkylthio)methylene]-3-oxo-N-o-tolylbutan-amides as thiolequivalents has been developed. Promoted by sodium hydroxide (NaOH) in ethanol at room temperature, the cleavage commences and the generated thiolate anions undergo nucleophilic addition in situ. β-Hydroxy sulfides were obtained in high yields along with good (3-regioselectivity
