Abstract

A one-pot procedure for the preparation of ammonia borane from trimethyl borate in 90% yield and> 99% purity has been reported. This methodology has been modified to prepare a series of trialkylamine–boranes in 70–82% yields from trimethyl borate and lithium hydride/aluminum chloride in the presence of the corresponding trialkylamine.
