Abstract
AbstractAddition of tBuOK to orange RuCl2(iPr2PCH2CH2NH2)2 forms the pink, square planar, Ru(II) complex Ru(iPr2PCH2CH2NH)2. This is an active catalyst (ToF 250 s−1) for the dehydropolymerization of H3B·NMeH2 to give high molecular weight polyaminoborane, [H2BNMeH]n (Mn = 138 700 g mol−1) at low loadings (0.03 mol%). An induction period observed is due to the initial formation of a hydroxy‐hydride species, Ru(iPr2PCH2CH2NH2)2(OH)(H), prior to fast turnover.
