Dehydrogenation of ammonia borane employing an air-stable, phosphine-free molecular nickel pincer catalyst

Herein, we report an air-stable, phosphine-free nickel catalyst supported by an NNN-based functionalized terpyridine ligand that enables the selective dehydrogenation of ammonia borane (AB). Operating under mild reaction conditions with low catalyst loading, achieves up to 2.58 equiv. of hydrogen evolution, while directing the reaction pathway toward borazine (BZ) formation.
