Desulfitative Suzuki Cross-Couplings of Arylsulfonyl Chlorides and Boronic Acids Catalyzed by a Recyclable Polymer-Supported N-Heterocyclic Carbene-Palladium Complex Catalyst

An effective and easy-to-handle process for the desulfitative Suzuki cross-couplings of arylsulfonyl chlorides and boronic acids in the presence of a recyclable polymer-supported NHC-Pd complex was developed. The supported catalyst could be reused several times with little loss of catalytic activity.
