phenyl rings systematically substituted with a NO2 group, Br and a OMe group (IIb-j), and derivatives of the same compound with phenyl groups systematically substituted with Me groups at positions 1 and 4 (IVk-m) have been prepared. The IR, NMR and electronic spectra of these compounds are in agreement with the assumed prevailing participation of the canonic structure of the aromatic type VIII α in their
脱水-3,5-双(苯硫基)2,6-二羟基-1,4-二苯基吡嗪二氢氧化物(IIa)的衍生物,其苯环对位的H原子被系统地取代为NO 2基团的Br和a制备了OMe基团(IIb-j),以及相同化合物的苯基在1和4位(IVk-m)上被Me基系统取代的衍生物。这些化合物的IR,NMR和电子光谱与假定的芳香族VIIIα的正构结构在其实际结构中的普遍参与相一致。
