Abstract

Thumbnail image of graphical abstract

Enders' N-heterocyclisches Carben (NHC) dehydriert den Ammoniak-Boran-Komplex mit einer vergleichsweise niedrigen Aktivierungsbarriere zu NH2BH2 und NHC-(H)2. Ein Nickel-NHC-Katalysator im Reaktionsmedium zersetzt das gebildete NHC-(H)2 in H2 und freies NHC, das wiederum Ammoniak-Boran-Komplex dehydrieren kann.
