Nitration of 3,5-dinitroaniline with 70% nitric acid yields 2,3,5-trinitrophenylnitramine ; this compound rearranges quantitatively on warming to give 4,g-dinitro-2-diazophenol and nitric acid.THE nitration of 3,5-dinitroanilineS under forcing conditions, gives pentanitroaniline,l the reaction probably proceeding via a series of Bamberger rearrangements, i.e., the formation of a nitramine and its subsequent rearrangement to a C-nitroaniline.Whilst examining the nitration of a series of nitroanilines, under widely varied conditions, we isolated a compound, in 65% yield, from the reaction of 3,bdinitroaniline with 70% HN03-98% H,S04, which was neither a nitramine nor
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.
