Ammonia borane (AB, NH3-BH3) was activated selectively on the boron hydrogen atoms by [Ir(dppm)2]OTf, as shown by variable-temperature 31P, 11B and 1H NMR studies, to yield cis- and irans-[Ir(H)2(dppni)2] OTí dihydrides, X-ray crystal structures of these complexes were obtained. DFT calculations suggest: the key reaction intermediate to be a Lewis base (L) stabilised adduct, cis-[Ir(H) (BH2.L) (dppm) 2]+ © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
