Abstract:The acid-catalyzed hydrolysis of tetrarnethoxyethene to methyl dirnethoxyacetate in aqueous solution at 25OC was found to occur with the hydronium-ion catalytic coefficient kH+ = 0.454 M-' s-I, to give the solvent isotope effect k H -/ k D -= 3.15, and to provide a Bronsted relation based upon six carboxylic acids with the exponent a = 0.42. These data indicate that the reaction proceeds via rate-determining proton transfer from the catalyzing acid to an olefinic carbon atom of the substrate. They also show te… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
