In this study, the treatment of N-silyl-B-chloro-aminoborane was investigated. It was found that substoichiometric quantities of Me3SiOTf led to B-N coupling, whereas activation with 5 mol% of Ag[Al{OC(CF3)(3)}(4)] resulted in Cl/Me exchange between the boron and the silicon center. Combined experimental and computational studies supported a chain reaction initiated by nucleation-limited chloride abstraction in the latter process.
