A highly chemoselective, efficient and nano-Pd catalyzed protocol for the rapid construction of sulfoxides and sulfones via the oxidation of symmetrical and unsymmetrical sulfides using H2O2 as an oxidant has been developed, respectively. The ready availability of starting materials, easy recovery and reutilization of the catalyst, wide substrate scope, and high yields make this protocol an attractive
已经开发出一种高度化学选择性,高效和纳米钯催化的方案,分别通过使用H 2 O 2作为氧化剂,通过对称和不对称硫化物的氧化来快速构建亚砜和砜。起始材料的可用性,催化剂的易于回收和再利用,广泛的底物范围以及高收率使得该方案成为有吸引力的替代方案。该方法还涉及无金属和微波促进的对称的二芳基硫醚的合成,以及FeCl 3介导的芳族重氮四氟硼酸盐与Na 2 S·9H 2的反应制备对称的二芳基二硫化物。O作为硫源。另外,经由K 2 CO 3介导的四氟硼酸壬二唑鎓与对称的二硫化物的反应产生了不对称的硫化物。
