Abstract An efficient and highly selective procedure for oxidation of sulfides to sulfoxides with N‐bromosuccinimide (NBS) in the presence of hydrated silica gel has been developed. Hydrated silica gel supplies the water necessary for decomposition of the intermediate bromosulfonium salt to the product, allowing the reaction to employ a nonaqueous media. Also, this procedure has increased the scope
摘要 开发了一种在水合硅胶存在下用 N-溴代琥珀酰亚胺 (NBS) 将硫化物氧化成亚砜的高效且高选择性的方法。水合硅胶为产物提供中间体溴锍盐分解所需的水,使反应能够使用非水介质。此外,该过程通过氧化更广泛的硫化物扩大了反应范围,这在以前是不可能的。
