The effects of γ-radiolysis on adamantane, perdeuterated adamantane, diamantane, 1- and 2-chloroadamantane, 1- and 2-bromoadamantane, 1-cyanoadamantane, 1- and 2-adamantanol, 1- and 2-adamantylamine have been examined via electron spin resonance techniques, and the nature of the predominant species produced is discussed. Spin-scavenging experiments using 2-methyl-2-nitrosopropane have been used, together with previously reported Br2 scavenging experiments, to identify the nature of the predominant species produced when purified solid adamantane is subjected to radiolysis. Data indicate that this is the 1-adamantyl radical. A possible reason for the controversial nature of data on this subject reported previously by other investigators is given.
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.
