| Abstract: | The relative reactivity of 1,2,3-triphenylbenzene (20 with reference to benzene), and the partial rate factors for NO2 substitution in positions 4,4′, and 4″ (18·6, 30, and 22·8 respectively) were determined by competitive nitration. The results suggest ‘conjugation effect’ as the factor responsible for the observed orientation and reactivity of the hydrocarbon in spite of its marked nonplanarity. |
