By employing a readily available CuCl/DDQ catalyst system, we herein report a direct C(sp3)–H sulfonylation of xanthene derivates with odorless sodium sulfinates. Various 9H-xanthenes, thioxanthenes, and 9,10-dihydroacridines are efficiently transformed into the desired benzylic sulfonyl products via a radical/radical cross-coupling process, proceeding with the merits of broad substrate scope, operational simplicity, good functional group compatibility, and mild reaction conditions.
