value in synthetic chemistry and bioscience. To pursue a sustainable approach for such a synthesis, an aerobic oxidative coupling method for the efficient preparation of organic disulfanes, using a low-toxic natural gallic acid as an organocatalyst, inexpensive MnCO3 as a cocatalyst, O2 as the terminal oxidant and water as the solvent, has been successfully developed. Such metal–organic cooperative catalytic
硫键的形成在合成化学和生物科学中具有重要的意义和价值。为了寻求一种可持续的合成方法,一种需氧氧化偶联方法可有效地制备有机二硫,使用低毒的天然没食子酸作为有机催化剂,廉价的MnCO 3作为助催化剂,O 2作为末端氧化剂和水作为溶剂,已经成功开发。这种金属-有机协同催化方案可以以高达99%的收率获得各种对称和不对称的二硫烷。具有实际便利性和低催化剂负载量的革兰氏合成进一步说明了我们方法的实用性。
