ABSTRACT:
The invention relates to novel 3-chloromethylsulfonylmethyl-4-sulfomethyl-pyrrolidinium betaines (chloromethylsulfonyl-sulfobetaines) of the general formula I and to processes for the preparation thereof. The compounds according to the formula I can be used as organic intermediates for further syntheses or, if they contain a long-chain alkyl radical, as polyfunctional surfactants. Molar quantities of diallylammonium chloride are reacted with dichloroacetic acid and twice the molar quantity of sodium hydrogen sulfite in the presence of a catalytic quantity of a peroxodisulfate and, after the addition of a catalytic quantity of iodide, the reaction solution obtained is converted by heating to 3-chloro-methylsulfonylmethyl-4-sulfomethyl-pyrrolidinium betaines (chloromethylsulfonyl-sulfobetaines) of the general formula I. ##STR1##
