The reaction between alkyl nitrites, particularly n-butyl nitrite, and tertiaryaromaticamines under a variety of experimental conditions promptly yielded products of N-dealkylation-N-nitrosation, ring nitration, ipso-substitution and, occasionally, combinations of these processes. Aminoethers were detected as final products and intermediates on the way to N-nitrosations. Reaction pathways are suggested
