Abstract:The Beckmann rearrangement reactions generally require strong acids, and always suffer from harsh conditions and serious environmental pollutions which go against the principle of green chemistry. Base on the green zinc catalyst, highly efficient catalytic reaction of ketoxime by Beckmann rearrangement was developed. The acid-additives-free reactions proceed under mild conditions, and show broad functional-group compatibility. Moreover, through this highly active and available zinc catalyst, the Beckmann rearr… 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.
