the direct coupling of sulfonic acid salts with amines and alcohols using the reagenttriphenylphosphine ditriflate is described. A new reusable polymer-supported reagent for these transformations under heterogeneous conditions is also described. These methods provide a fundamentally new approach to making small molecules containing the sulfonamide functional group.
