The aromatic odd-alternant phenalenylanion and a number of its derivatives were prepared in order to study the perturbation of this conjugated anion by methyl and methoxy groups. The conjugated anions were studied by means of 1H and 13C NMR spectrometry, alkylation experiments and semi-empirical calculations. It was found that a substituent at a charged carbon atom perturbs the entire conjugated system
为了研究该共轭阴离子对甲基和甲氧基的扰动,制备了芳香族奇数交替的菲烯基阴离子及其许多衍生物。通过1 H和13 C NMR光谱,烷基化实验和半经验计算研究了共轭阴离子。发现带电碳原子上的取代基扰乱了整个共轭体系,而无活性(不带电)碳原子上的取代基对取代基邻位的影响很大。
