An efficient general synthetic approach giving a facile, rapid and inexpensive access to a wide range of novel 1,2,3-triazoles bearing closo-dodecaborate fragment has been developed. The method is based on the nucleophilic cleavage of oxonium dodecaborate with NaN3 or tertiary propargylamine and subsequent Huisgen 1,3-dipolar cycloaddition ("click" methodology) of the cleavage products and organic acetylenes or azides.
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.
