... resonance structure [16] (which has a stabilizing effect for Ar-3 substitution in the other heterocycles) less effective. ... nitration of 1, 3 and 4 is strongly in- fluenced by the size of the heterocyclic side ring ... at 4.37, 4.45, 4.47, 4.48 (m, 4H), 7.97 (d, J = 3 Hz, IH), 8.40 (d, J = 3 Hz, ...
