Recycling: A self‐contained procedure for the recycling of BNH‐waste, based on the three major steps: polymer break‐up, amine supported catalytic hydrodehalogenation of boron halogens, and the base exchange in borane amine adducts, is developed (see picture). Beyond the original task of recycling spentammoniaborane, the process provides a new means to produce borohydride species efficiently, by the

This paper reports a complete ammoniaborane (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.
