Synthesis and characterization of a novel hydrido-alkyl complex of rhodium(III) formed by intramolecular activation of a benzylic C-H bond: Trans-bis[N-methyl-N-propionyl-2-(diphenylphosphino)benzylamine] hydridorhodium(III) hexafluorophosphate

The phosphine N-methyl-N-propionyl-2-(diphenylphosphino)benzylamine (1), reacting with the precursor complex [Rh(NBD)L][PF6] (L = 1, NBD = 2,5-norbornadiene) and molecular hydrogen under ambient conditions, undergoes chelate-assisted C-H bond activation at the benzylic position, quantitatively yielding the five-membered chelate complex trans-[RhH(P(C6H4-o-(CH2N(CH 3)COCH2CH3))(C6H5) 2)(P(C6H4-o-(CHN(CH3)COCH 2CH3))(C6H5)2)]-[PF 6] (4). Extensive spectroscopic studies demonstrate that the rhodium is located in the center of a square bipyramid with an apical hydrogen.
