benzenethiols. The method involves copper(I) iodidecatalyzed coupling of thiols with H-phosphonates in the presence of triethylamine. The reaction proceeds effectively to afford the corresponding thiophosphates in moderate to good yields via an aerobic dehydrogenative coupling of H-phosphonates with benzenethiols. This method is easy, rapid, and good-yielding for the synthesis of thiophosphates from benzenethiols
A catalyst-free synthesis of phosphorothioatesvia a P–S cross-coupling reaction of thiols with dialkyl phosphites has been studied. With presented method, various phosphorothioates were obtained by the reaction of thiols with H-dialkyl phosphites in the presence of DMSO as both solvent and oxidant under transition-metal-free conditions. Mechanistic studies showed that the reaction proceeds with formation
