Mechanism of substitution at a boron atom. Part II. Kinetics of reaction of o-nitroamines with boron halides
Abstract
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.
