Реакции карбоксилсодержащих соединений и их солей с полифторалкилсульфитами

Polyfluoroalkylchlorsulfites react with sodium salts of carboxylic acids yielding the mixed anhydrides of carboxylic and polyfluoroalkylsulphurous acids, whereas carboxylic group in carboxylic acids and olygomers of ƒ-aminocaproic acid in the presence of triethylamine, form polyfluoroalkyl esters and by-products of the reaction: sulfur dioxide and triethylamine hydrochloride.
