estimated on the base of the observed reaction times. A strong opposite effect of substituents located at position para to the nitroso group and those located para to the amino group in the side ring was observed. Mechanistic explanation, based on the electronic properties of the substituents and their mesomeric effects, was presented. The usefulness of the obtained data for the designed syntheses of
