Abstract

Ammonia borane dehydrogenation can be catalyzed by a number of organometallic species. [Ir(κ²-I^tBu) ₂][PF₆] (I^tBu = 1,3-bis(tert-butyl)imidazol-2- ylidene) is the most active catalyst for this process that has been reported to date. We explore herein the absolute limits of the use of this and related complexes, including [Ir(κ²-I^tBu) ₂][BAr^F₄], [Ir(H)₂(I ^tBu)₂][BAr^F₄], and [Ir(κ²-I^tBu)₂(NH₃)][BAr ^F₄] (BAr^F₄ = tetrakis(3,5- bis(trifluoromethyl)phenyl)borate).
