In this study, a facile CuI catalyzed synthesis of sulfones involving a nucleophilic addition of functionalized organozinc reagents to organic sulfonylchlorides is realized. This reaction proceeds efficiently at room temperature, giving rise to various functional group substitutedsulfones, generally in moderate to high yields. The method provides a novel, simple, and promising strategy for functionalized
