摘要
The direct sulfonamidation of primary and secondary benzylic alcohols catalyzed by a 2,3,4,5-tetrafluorophenylboronic acid/oxalic acid co-catalytic system was examined. The reaction proceeds under mild conditions with readily available starting materials and has been shown to be gram-scalable without significant decrease of yield. Both primary and secondary benzylic alcohols were evaluated and afforded the desired sulfonamide products with good to excellent yields.
