ABSTRACT:
There are provided compounds which are alkyl sulfonates substituted on a 5-membered heterocyclic or cyclic ring. The hetero-substituents of the ring may be O, S, R.sub.2 N, R.sub.3 R.sub.4.sup.+ N<, ##STR1## where R.sub.2, R.sub.3 and R.sub.4 are the same or different substituted or unsubstituted, and are hydrogen, alkyl or aryl. Optionally, the hetero-substituent may be replaced by R.sub.3 R.sub.4 C. The alkyl sulfonate substituent is in the 3 position of the ring and a substituted or unsubstituted alkyl substituent is in the 4 position of the ring. The compounds may be prepared by reacting X(CH.sub.2 CH.dbd.CHR).sub.2, where X is the above mentioned hetero-substituents or R.sub.3 R.sub.4 C<, with a bisulfitc salt.
