Abstract

Three isomeric N,N,N,-trimethylanilinium oxides were subjected to nitration, bromination and diazocoupling. The purpose was to investigate the activating effects of the oxide function on ring electrophilic substitution. This was performed in the presence of the deactivating trimethylammonium function in the three isomers. The directive influence of these isomers on the newly entering groups was also investigated.
