The catalytic activity in amine-borane dehydrogenation is shown for the first time for Ln(II) species using complexes [{(Bu-CH)CH}M·L] (M = Yb, Sm, L = (DME), TMEDA). The protonation of M(II)-C bonds with HNRRBH affords amidoborane complexes [M(NRRBH)L], which under excess HNMeBH transform to [NMeBHNMeBH] derivatives, both serving as the dehydrocoupling intermediates.
首次使用配合物[{(Bu-CH)CH}M·L]（M = Yb，Sm，L = (DME)，TMEDA）展示了Ln(II)物种在胺硼烷脱氢反应中的催化活性。用HNRRBH使M(II)-C键质子化得到氨基硼烷配合物[M(NRRBH)L]，在过量HNMeBH存在下，该配合物会转化为[NMeBHNMeBH]衍生物，二者均作为脱氢偶联中间体。
