Enders' N‐heterocyclic carbene (NHC) dehydrogenates ammonia–borane with a relatively low barrier, producing NH 2 BH 2 and NHC–(H) 2 . The nickel NHC catalyst present in the reaction media can activate the NHC–(H) 2 produced to regenerate the free NHC and release H 2 . The release of free NHC enables further dehydrogenation of ammonia–borane.
