Palladium-catalyzed desulfitative C-H arylation of azoles with sodium sulfinates.

A palladium-catalyzed desulfitative C-H arylation of azoles with sodium sulfinates using Cu(OAc)(2)·H(2)O as oxidant has been discovered. The reaction proceeded well for a range of different substrates under oxidative conditions. A series of aryl-substituted azoles have been synthesized in moderate to good yields.
