3-Methyl-1:12-benzoperylene, 4-methyl-1:12-benzoperylene and 3,10-dimethyl-1:12-benzoperylene have been synthesized. The protons in the ABX systems of perylene have different coupling constants whilst in 1:12-benzoperylene JXB, JAB, JBA and JBX are equal. This is explained by the formulation with aromatic sextets. The NMR spectra of the Me derivatives support this formulation. The comparison of the
合成了3-甲基-1:12-苯并per,4-甲基-1:12-苯并per和3,10-二甲基-1:12-苯并per。per的ABX系统中的质子具有不同的偶合常数,而在1:12-苯并per中,J XB,J AB,J BA和J BX相等。这是由具有芳香六重体的配方解释的。Me衍生物的NMR光谱支持该配方。对苯并戊烯和1:2-苯并戊烯与1:12-苯并per及其及其苯甲酸酯的核磁共振谱的比较表明,该苯并戊烯配合物中的环电流很强,这可能与“超芳香性”有关。
