A variety of sulfides and disulfides were converted into the corresponding sulfoxide derivatives with 70% t-BuOOH (water) as the oxidant in the presence of catalytic quantity of CuBr2. The method described does not involve cumbersome work-up, has wide range of applicabilities, exhibits chemoselectivity, and proceeds under mild reaction conditions, and the resulting products are obtained in good yields
oxidant in the presence of catalytic quantity of silver nitrate. The method described has a wide range of application, does not involve cumbersome workup, exhibits chemoselectivity, and proceeds under mild reaction conditions, and the resulting products are obtained in good yields within a reasonable time. oxidation - sulfide - sulfoxide - silver nitrate - tert-butyl hydroperoxide
