Base-induced bromination of tri-exo-norbornylborane: an electrophilic substitution with predominant inversion of configuration

Abstract
The reaction of bromine with tri-exo-norbornylborane under the influence of methanolic sodium methoxide results in inversion of configuration at carbon during the electrophilic substiution to give predominantly endo-bromonorborane (75 ± 5%endo).
