form aziridines is offered in terms of orbital interactions between the distant groups and the olefinic bond, making the latter remarkably electron deficient as evidenced by UV-photoelectron spectrosoopy. Because of the complexity of the spectra, identification of the Ip associated with the reactive π-centre was made by recourse to ab initio configuration interaction calculations for key members of the
一系列双环烯烃与腈的反应性受到远程官能团性质的深刻影响。与邻苯二甲it苯丁烯相比,与羧乙氧基亚硝苯的反应明显缺乏反应性,苯二甲亚it苯丁烯具有明显的亲核性质。根据远距离基团与烯键之间的轨道相互作用,提供了不愿形成氮丙啶的解释,这是由紫外光电子能谱法证明的,后者明显缺乏电子。由于光谱的复杂性,通过依赖于该系列关键成员的从头开始构型相互作用计算来确定与反应性π中心相关的Ip 。
