We report the atom-economic and environmentally friendly synthesis of Z-β-sulfonyl-a,β-unsaturated carbonyl compounds in water. The mechanism study reveals that the hydrosulfonylation of alkynylcarbonyl compounds with sulfinic acids proceeds via a mechanism that features a sulfinic acid molecule protonating an alkynyl motif to form the ethenium intermediate, which subsequently reacted with a sulfonyl
我们报告了水中Z -β-磺酰基-a,β-不饱和羰基化合物的原子经济和环境友好合成。机理研究表明,炔基羰基化合物与亚磺酸的氢磺酰化反应是通过一种机理进行的,该机理的特征是亚磺酸分子使炔基基元质子化,从而形成乙烯中间体,随后该中间体与磺酰基阴离子反应,得到所需的产物。乙烯中间体可区分炔烃底物C bondC三键上两个取代基之间的电子和空间需求,以显示来自多种Z -β-磺酰基-a,β-不饱和羰基化合物的高区域选择性和立体选择性。
