Production of Amidinyl Radicals via UV–Vis-Light Promoted Reduction of N-Arylthiophene-2-carboxamidoximes and Application to the Preparation of Some New N-Arylthiophene-2-carboxamidines
Abstract:A modern
method for the preparation of some new N-arylthiophene-2-carboxamidines via amidinyl radicals
generated using UV–vis-light promoting the reduction of N-arylthiophene-2-carboxamidoximes without any catalyst
in a short amount of time, highly straight forward, and in an efficient
manner is described. This method defeats the flaws of the conventional
methods for the reduction of amidoxime derivatives to amidine derivatives,
which require harsh conditions such as using a strong acid, high temperature,
and … 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.
