A catalyst-free sulfonylation reaction of activated alkenes with sulfonyl hydrazides was efficiently developed under mild and environmentally benign conditions, in water without any ligand or additive. The reaction gave a range of structurally diverse mono-substituted ethyl sulfones with excellent yields, in which the by-product was nitrogen.
在温和且环境友好的条件下,无需任何配体或添加剂,在水中高效开发了活化烯烃与磺酰肼的无催化剂磺酰化反应。该反应以优异的产率提供了一系列结构多样的一取代乙基砺,副产物为氮气。
