Palladium-Catalyzed Site-Selective C−H Functionalization of Weakly Coordinating Sulfonamides: Synthesis of Biaryl Sulfonamides
A novel and site selective C−Hfunctionalization of unsubstituted sulfonamides has been developed for the synthesis of ortho aryl sulfonamides. The reaction involves highly regioselective ortho mono arylation of weakly coordinating SO2NH2 directing group by means of aryl iodides. Palladium acetate in the presence of silver(I) oxide is found to be the most effective catalytic system.
