Abstract
The kinetics of oxidation of allyl alcohol with potassium bromate in the pr esence of osmium(VIII) catalyst in aqueous acid medium has been studied und er varying conditions. The active species of oxidant and catalyst in the re action were understood to be Bro(3)(-) and H2OsO5, respectively. The autoca talysis exhibited by one of the products, that is, Br-, was attributed to c omplex formation between bromide and osmium(VIII). A composite scheme and r ate law were possible. Some reaction constants involved in the mechanism ha ve been evaluated. (C) 1999 John Wiley & Sons, Inc.
