Dehydrogenation of iron amido-borane and resaturation of the imino-borane complex

We report on the first isolation and structural characterization of an iron phosphinoimino-borane complex Cp*Fe(η(2)-H(2)B[double bond, length as m-dash]NC(6)H(4)PPh(2)) by dehydrogenation of iron amido-borane precursor Cp*Fe(η(1)-H(3)B–NHC(6)H(4)PPh(2)). Significantly, regeneration of the amido-bor...

description We report on the first isolation and structural characterization of an iron phosphinoimino-borane complex Cp*Fe(η(2)-H(2)B[double bond, length as m-dash]NC(6)H(4)PPh(2)) by dehydrogenation of iron amido-borane precursor Cp*Fe(η(1)-H(3)B–NHC(6)H(4)PPh(2)). Significantly, regeneration of the amido-borane complex has been realized by protonation of the iron(ii) imino-borane to the amino-borane intermediate [Cp*Fe(η(2)-H(2)B–NHC(6)H(4)PPh(2))](+) followed by hydride transfer. These new iron species are efficient catalysts for 1,2-selective transfer hydrogenation of quinolines with ammonia borane.
