Reactions of amine-boranes NH(3)BH(3), Me(2)NHBH(3), or Me(3)NBH(3) with AlX(3) (X = Cl, Br, I, C(6)F(5)) have been examined. The species AlBr(3)·H(3)BNMe(3), Al(C(6)F(5))(3)·H(3)BNMe(3), Al(C(6)F(5))(3)·H(3)BNHMe(2) and Al(C(6)F(5))(3)·H(3)BNH(3) have been prepared and isolated. The analogous reaction of B(C(6)F(5))(3) and H(3)BNMe(3) results in C(6)F(5)-transfer and the formation of (C(6)F(5))BH(2)·NMe(3). While the adduct was unreactive to CO(2), species reacts with CO(2) to give the formate linked Al(C(6)F(5))(3)(HCO(2))H(2)BNMe(3). The species R(3)PC(OAl(C(6)F(5))(3))(2) (R = o-tol (), R = Mes ()) were prepared, and was shown to react with amine-boranes to effect the reduction of this bound-CO(2) to formate and methoxide-derivatives, proceeding through intermediates including and [(Me(3)NBH(2))(2)(μ-H)][(HCO(2))(Al(C(6)F(5))(3))(2)] . The salt [tBu(3)PH][(HCO(2))(Al(C(6)F(5))(3))(2)] was prepared independently.
