Abstract

Abstract Cupric acetate in ionic liquids (ILs) catalyzes coupling reaction of arylboronic acids with sulfinic acid salts to afford aryl sulfones in good yields under ambient conditions. This mild and efficient cross-coupling reaction gives access to a wide range of alkylaryl and diaryl sulfones in good yields. The use of ionic liquid allows for easy separation of the product and recycling of copper catalyst.
