N-fluoro perfluoroheterocyclic sulfonamides of the following Formula I <IMAGE> (I) wherein Hetf represents an aromatic perfluoroheterocyclic radical of valency n and each R independently represents a substituted or unsubstituted C1-C30 alkyl, C6-C14 aryl substituted C1-C10 alkyl, C6-C14 aryl, or C1-C10 alkyl substituted C6-C14 aryl group, are novel electrophilic fluorinating agents. Preferably Hetf is a perfluorinated nitrogen-containing aromatic group, especially pyridyl, pyrimidinyl, pyrazinyl or 1,3,5-triazinyl; n is 1; and R is perfluorinated, especially trifluoromethyl.
