The reaction of 2,4-dinitronaphthylamine with phenylboron dichloride and related reactions have been studied kinetically. Substitution by an SN2 pattern, or via an unstable intermediate is a possible mechanism. The energetics of boronium ion formation are discussed in relation to these mechanisms.
动力学研究了2,4-二硝基萘胺与二氯化苯硼的反应及相关反应。可能是通过S N 2模式或不稳定的中间体取代。结合这些机理讨论了硼离子形成的能量学。

A comparison is made of the elimination of hydrogen chloride from certain adducts of arylamines with dichloro(phenyl)borane and the corresponding arylammonium trichloro(phenyl)borates, with previous data on related boron trichloride adducts.1 Between 1 and 2 of the theoretical number of mol of hydrogen chloride are evolved from dichloro(phenyl)borane systems, exactly 2 mol from the trichloro(phenyl)borates
