Abstract
An intermolecular alkylation of sulfonamides with trichloroacetimidates occurs in refluxing toluene without additives. Unsubstituted sulfonamides provide better yields than more encumbered N-alkyl sulfonamides, whereas the trichloroacetimidate alkylating agent must be a stable cation precursor.
