[摘要]：Cupric acetate in ionic liqs. (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 liq. allows for easy sepn. of the product and recycling of copper catalyst.
