Ammonia–Borane and Amine–Borane Dehydrogenation Mediated by Complex Metal Hydrides

This review is a comprehensive survey of the last 10 years of research on ammonia–borane and amine–borane dehydrogenation mediated by complex metal hydrides (CMHs), within the broader context of chemical hydrogen storage. The review also collects those cases where CMHs are the catalyst spent form or its resting state. Highlights on the reaction mechanism (strictly dependent on the CMH of choice) and the catalysts efficiency (in terms of equivalents of H2 produced and relative reaction rates) are provided throughout the discussion.
