naphthalene-1-diazonium cations all show short attractive interactions between an electron-rich atom of the peri-substituent and the α -N-atom of the diazonium group. These are interpreted as models for incipient nucleophilic attack on a NN bond. The diazonium group is a better acceptor of electron density ‘through space’ than the NO2 group, which parallels their relative ‘through-σ-bond’ inductive effects.
四个被周围取代的
萘-1-重氮阳离子均显示出在周围取代基的富电子原子与重氮基团的α-N原子之间的短暂吸引相互作用。这些被解释为对NN键的初期亲核攻击的模型。与NO 2基团相比,重氮基团是更好的电子密度“穿透空间”受体,这与它们的相对“穿透-σ-键”感应效应平行。
