title: Pd-catalyzed direct C-H bond sulfonylation of azobenzenes with arylsulfonyl chlorides.
abstract: Pd(II)-catalyzed C-H sulfonylation of azobenzenes with arylsulfonyl chlorides has been developed. The sulfonylazobenzenes were obtained in moderate to excellent yields for 28 examples. This protocol features high efficiency, wide functional group tolerance, and atom economy.
