The pincer d8-monohydride complex RhH-{xant(PiPr2)2} (xant(PiPr2)2 = 9,9-dimethyl-4,5-bis-(diisopropylphosphino)xanthene) promotes the release of 1 equiv of hydrogen from H3BNH3 and H3BNHMe2 with TOF50% values of 3150 and 1725 h−1, to afford [BH2NH2]n and [BH2NMe2]2 and the tandem ammonia borane dehydrogenation−cyclohexene hydrogenation.
