Not a bit like his brother: DFT studies show that ammonia–borane dehydrogenations by iridium pincer complexes occur by concerted hydride and proton transfer from ammonia–borane to the catalyst, not through BH activation and subsequent β-hydride elimination from the nitrogen end, as had been suggested. Such a concerted dehydrogenation pathway does not exist for ethane, which is isoelectronic with ammonia–borane.
