| Abstract: | An Efficient NH2SO3H-catalyzed direct alkylation of active methylene compounds with benzylic and allylic alcohols has been reported.The alkylation was carried out in the presence of only sub-stoichiometric amount of NH2SO3H(10mol%) under reflux in dichloroethane in high to excellent yields.It's an easy handling reaction as the water was obtained as the only side product. |
