ABSTRACT:
The invention relates to novel sulfobetaine-substituted .alpha.-sulfonylcarboxylic acids of the general formula I and to processes for the preparation thereof. As organic intermediates, the compounds according to formula I represent a reactive synthesis component having the character of a sulfobetaine and can be used for further syntheses. In the case of a long-chain alkyl radical R.sub.1, polyfunctional surfactants are obtained. According to the invention, molar quantities of diallylammonium chloride are reacted with chloroacetic acid and twice the molar quantity of sodium hydrogen sulfite in the presence of a catalytic quantity of a peroxodisulfate, and the reaction solution obtained is converted, after addition of a catalytic quantity of iodide, by heating into sulfobetaine-substituted .alpha.-sulfonylacetic acids according to the general formula I. ##STR1##
