electronic spectra of the chiral, donor-acceptor (push-pull) chromophores (±)-4 and (±)-5 with a 6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine scaffold (Scheme 1 and Fig. 2). The electronic structures of these compounds were investigated at a quantum-chemical level (Figs. 2 and 3). The chemical reactivity of 6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine ((±)-11) towards aromatic electrophilic substitution
我们报告了具有6 H,12 H -5,11-methanodibenzo [ b,f ]的手性,供体-受体(推挽)发色团(±)-4和(±)-5的合成和电子光谱。[1,5]重氮素支架(方案1和图2)。这些化合物的电子结构在量子化学水平上进行了研究(图2和3)。6 H,12 H -5,11-甲二苯并[ b,f ] [1,5]重氮电影((±)-11)对芳族亲电子取代的化学反应性(方案2和表1)提供了有关其电子结构的更多信息,并证实了在该杂环系统中桥头N原子的孤对的不可忽略的离域。
