Abstract: The addition reactions of thiol anions to form adducts with acrylonitrile (l), 1- chloroacrylonitrile (2), and fumaronitrile (3) and the corresponding elimination reactions were examined in aqueous solution, generally containing 8.3% Me2S0 at 25 OC. Deuterium exchange into the methanethiol and thiosalicylate adducts of 1 is faster than elimination. Deuterium exchange causes biphasic kinetics for elimination reactions in D20 of the p- ...
