A process of removing soil and/or stains from fabrics by immersing the fabrics in a peroxygen bleach bath containing as a peroxygen activator an heterocyclic sulfonate ester wherein the heterocyclic moiety includes a 5 to 6 membered heterocyclic ring containing 1 to 3 hetero atoms selected from the class consisting of --N--, --O-- and --S-- and the sulfonic acid is selected from the class consisting of an alkanesulfonic acid of 1 to 18 carbon atoms and an arenesulfonic acid of the benzene and naphthalene series. Also described are dry blend compositions containing the activator and peroxygen.

mechanism involving a pentavalentintermediate for poorer leaving groups to a fully concerted mechanism for good leaving groups and supported by a theoretical study. In the present work, we have performed a detailed computational study of the hydrolysis of these compounds and find no computational evidence for a thermodynamically stable intermediate for any of these compounds. Additionally, we have extended
