Reductive dechlorination of BCl3 for efficient ammonia borane regeneration

Abstract

This paper reports a complete ammonia borane (AB) regeneration process in which Bu₃SnH was utilized as a reductant for the reductive dechlorination of BCl₃, and Et₂PhN was selected as a ‘helper ligand’ to generate Et₂PhN·BH₃, which gives rise to a high yield of AB by a base-exchange reaction at ambient temperature.
