A General Procedure for the Construction of 2-Alkyl-Substituted Vinyl Sulfonyl Fluoride

Abstract

A series of compact and multifunctional 2-alkyl-substituted vinyl sulfonyl fluorides were efficiently prepared from the corresponding alkyl iodides and 2-chloroprop-2-ene-1-sulfonyl fluoride (CESF). This Giese-type radical approach provided new and general access to alkenyl sulfonyl fluorides, including structures that would otherwise be challenging to synthesize with previously established methods. A correspondingly large collection of derivatization reactions was also demonstrated on the alkenyl sulfonyl fluorides.
