Ammonia borane (AB) has high hydrogen density (19.6 wt%), and can, in principle, release up to 3 equivalents of H2 under mild catalytic conditions. A limited number of catalysts are capable of non-hydrolytic dehydrogenation of AB beyond 2 equivalents of H2, but none of these is shown directly to derivatize borazine, the product formed after 2 equivalents of H2 are released. This talk will discuss the design and development of 1, a structurally-simple, yet high productivity catalyst that is capable of borazine dehydrogenation, and thus exhibits among the highest H2 productivity known for anhydrous AB dehydrogenation.
