Abstract
The title reaction is the first order in [NCS] in the presence of palladium (II) catalyst. The order in [allyl alcohol] is less than unity whereas that in [Pd(II)] is unity. Increase in [OH-) accelerates the reaction rate whil e added product, succinimide, retards the reaction rate. Increase in ionic strength and t-butanol content in reaction medium have negligible effect. T he mechanism involving the hypochlorate ion as the reactive species of the oxidant has been proposed. The reaction constants of individual steps invol ved in the reaction mechanism have been evaluated.
