A diverse chemoselective insertion reaction of sulfoxonium ylides and thiosulfonates under transition-metal-free conditions is developed, which successfully affords 1,4-diketone compounds, arylthiosulfoxide-ylides, and β-keto thiosulfones, respectively. The nucleophilic addition of two molecular sulfoxonium ylides to construct sulfone-substituted 1,4-dione compounds is the highlight of this work.
在无过渡金属的条件下,开发了亚硫酸盐和硫代磺酸盐的多种化学选择性插入反应,分别成功地获得了1,4-二酮化合物,芳基硫代亚砜和β-酮基硫代砜。这项工作的重点是两个分子亚砜基的亲核加成反应,以构建砜取代的1,4-二酮化合物。
