Abstract
A variety of functionalized β-keto sulfones were smoothly prepared through oxysulfonylation of commercially available alkynes with sulfonylhydrazides under the synergistic interactions of visible light irradiation, Ru(bpy)3Cl2 photocatalyst, oxygen, KI, and NaOAc basic additive under very mild reaction conditions.
摘要
在可见光照射、Ru(bpy)₃Cl₂光催化剂、氧气、碘化钾和醋酸钠碱性添加剂的协同作用下，在非常温和的反应条件下，通过市售炔烃与磺酰肼的氧磺酰化反应，顺利制备了多种功能化的β-酮砜。
