We present evidence that the reactions of ethenesulfonyl chloride (1) and trans-1-propene-1-sulfonyl chloride (3) with water in the presence of pyridine, trimethylamine, and a number of other tertiary amines proceed primarily by way of an initial vinylogous substitution reaction to form the cationic sulfene, , which subsequently reacts with water either by addition (and deprotonation) to form the betaine

The preparation of 2-hydroxyethanesulphonylchloride (1), the first example of compound containing both sulphonylchloride and primary alcohol functions, is described; reaction of (1) with base gives products evidently derived from the sulphene (4) and the β-sultone (6).
