Primary hydroxy groups as in neopentyl alcohol 7 or neopentylglycol 18 react readily with perfluorobutanesulfonyl fluoride 1 in the presence of 2 equiv. of the nucleophilic 4-dialkylaminopyridines 4 to afford high yields of the corresponding N-alkyl-4-dialkylaminopyridinium perfluorobutanesulfonates (nonaflates).Secondary hydroxy groups give rise to a mixture of the corresponding olefins and monofluorides as well as of the corresponding N-alkyl-4-dialkylaminopyridinium nonaflates.
