Palladium(II)-Catalyzed Acetoxylation and Chlorination of 2-Alkenyl <i>p</i>-Tolyl Sulfones

Abstract

Abstract 2-Alkenyl p-tolyl sulfones were converted into the corresponding 3-acetoxy(or chloro)-1-alkenyl p-tolyl sulfones via π-allylpalladium complexes which reacted regiospecifically with a nucleophile such as acetate anion or chloride anion in the presence of Cu(II).
