A simple and efficient method for the preparation of thiophosphates from benzenethiols involves copper(I) iodide catalyzed coupling of thiols with H-phosphonates in the presence of triethylamine. The reaction proceeds effectively via an aerobic dehydrogenative coupling to afford the corresponding thiophosphates in good yields.
