DeBergh, J. Robb published the artcileSynthesis of Aryl Sulfonamides via Palladium-Catalyzed Chlorosulfonylation of Arylboronic Acids, Formula: C28H41N2P, the publication is Journal of the American Chemical Society (2013), 135(29), 10638-10641, database is CAplus and MEDLINE.
A palladium-catalyzed method for the preparation of sulfonamides is described. The process exhibits significant functional group tolerance and allows for the preparation of a number of arylsulfonyl chlorides and sulfonamides under mild conditions. E.g., in presence of the Pd catalyst I (L = ligand II), reaction of PhOSO2Cl with 4-methoxyphenylboronic acid, followed by reaction with morpholine, gave 95% sulfonamide III.
