Abstract

A mild and efficient copper-catalyzed cross-coupling reaction of arylboronic acids with sulfinic acid salts affords a wide range of alkylaryl and diaryl sulfones in good yields under ambient conditions. The use of an ionic liquid allows a convenient separation of the product and recycling of copper catalyst.
