The intramolecular isotope effects in the decarboxylation of C13 and C14 carboxyl-labeled malonic and bromomalonic acids have been determined. The observed C13 effects are in agreement with the results of other investigators; the C14 effects are in partial agreement with earlier published results of one of the authors. The ratio of C14 to C13 effects is found to be near 3.6.
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.
