abstract
Reactions of isomeric 4,6-dinitro-1- and 4,6-dinitro-2-phenylindazoles, as well as 4,6-dinitro-2-phenylbenzo[b]furan, with various aminating agents were studied under the vicarious nucleophilic substitution conditions. It was found that depending on the aminating system, the starting compounds undergo either selective mono-amination at position 7 or double amination.
