Radical addition reactions of bromomalononitrile to various alkenes using 2,2′-azobis(2,4-dimethyl-4-methoxyvaleronitrile) (V-70) were examined. The advantages of V-70 which is an effective radical initiator at low temperature in contrast to the other azobis compounds are described. Especially V-70L (the low melting point diastereomer) was found to be the best radical initiator.
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.
