Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The nitration and bromination of 6-methylindolo[2,3-b]quinoxaline take place in the 9 position. The reactivity indexes were calculated within the framework of the Hückel MO and CNDO (complete neglect of differential overlap) methods. Only the π-charge distribution is in satisfactory agreement with the experimental data on electrophilic substitution in the investigated compound.
