The Simplest Amino‐borane H(2)B=NH(2) Trapped on a Rhodium Dimer: Pre‐Catalysts for Amine–Borane Dehydropolymerization

The μ‐amino–borane complexes [Rh(2)(L(R))(2)(μ‐H)(μ‐H(2)B=NHR′)][BAr(F) (4)] (L(R)=R(2)P(CH(2))(3)PR(2); R=Ph, (i)Pr; R′=H, Me) form by addition of H(3)B⋅NMeR′H(2) to [Rh(L(R))(η(6)‐C(6)H(5)F)][BAr(F) (4)]. DFT calculations demonstrate that the amino–borane interacts with the Rh centers through stro...

description The μ‐amino–borane complexes [Rh(2)(L(R))(2)(μ‐H)(μ‐H(2)B=NHR′)][BAr(F) (4)] (L(R)=R(2)P(CH(2))(3)PR(2); R=Ph, (i)Pr; R′=H, Me) form by addition of H(3)B⋅NMeR′H(2) to [Rh(L(R))(η(6)‐C(6)H(5)F)][BAr(F) (4)]. DFT calculations demonstrate that the amino–borane interacts with the Rh centers through strong Rh‐H and Rh‐B interactions. Mechanistic investigations show that these dimers can form by a boronium‐mediated route, and are pre‐catalysts for amine‐borane dehydropolymerization, suggesting a possible role for bimetallic motifs in catalysis.
