Regio-, stereo-, and chemoselective ring opening of epoxides with thiols using Cu/MgO as a heterogeneous catalyst has efficiently been carried out to produce the corresponding β-hydroxy sulfides in excellent yields at room temperature under solvent-free conditions. The treatment of the epoxides with thiols and 50% aqueous H2O2 in the presence of the same catalyst at room temperature affords the β-hydroxy
使用 Cu/MgO 作为多相催化剂,环氧化物与硫醇的区域选择性、立体选择性和化学选择性开环已被有效地进行,以在室温和无溶剂条件下以优异的产率生产相应的 β-羟基硫化物。在室温下,在相同催化剂的存在下,用硫醇和 50% 的 H2O2 水溶液处理环氧化物以极好的收率提供了 β-羟基亚砜。
