Iodide Salt Mediated Synthesis of β‐Keto Sulfones Using Arylsulfonyl Chlorides as the Sulfur Sources

Abstract

AbstractAn efficient, green strategy has been developed to synthesize β‐keto sulfones using available and inexpensive sulfonyl chlorides as a sulfur source in reaction with aromatic alkenes in the presence of cheap iodide. It is particularly pointed out that this method involves the construction of C−S bonds and the desired product can be obtained either through the free radical pathway. This agreement involves a green and simple synthesis method, and is functionalized with styrene and the present method is applicable to a wide range of benzenesulfonyl chloride compounds and styrenes with a variety of functional groups.
