Jf. King et Ms. Gill, REVERSIBLE AND IRREVERSIBLE ELCB MECHANISMS IN THE HYDROLYSIS OF 2,2,2-TRIFLUOROETHANESULFONYL CHLORIDE - CARBANION INTERMEDIATES IN AQUEOUS ACID, Journal of organic chemistry, 63(3), 1998, pp. 808-811
Hydrolysis of 2,2,2-trifluoroethanesulfonyl chloride (1) is shown to t
ake place by way of the sulfene (CF3CH=SO2), formed by (a) an irrevers
ible E1cB process over the pH range 1.8-5 with water acting as the car
banion-forming base in the lower pH range and hydroxide anion at highe
r pH, and (b) a reversible E1cB reaction in dilute acid.
