The formation of
bromine azide from the bisazidobromate(I)
anion
or alternatively from Zhdankin’s reagent, using a phosphonium
bromide salt as a common starting point, is reported. After homolytic
cleavage in the presence of alkenes or alcohols either 1,2-functionalization
or alternatively the selective oxidation of secondary alcohols in
the presence of primary alcohols occur. The scopes and limitations
of the use of BrN3 are covered.
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.
