摘要：

(Figure Presented) 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. © 2007 Wiley-VCH Verlag GmbH & Co. KCaA.
