  Study of the Bonding Properties of the New Ligands C₅H₃N(2-R‘)(6-CH₂PPhR) toward Rhodium(I). Evidence for a Dynamic Competition for Bonding between O- and N-Donor Centers When R = o-Anisyl, R‘ = Me

  摘要：

  The bonding properties of the optically active chiral-at-P polydentate ligands C5H3N(2-R')(6-CH2PPhR) (R = Me, R' = H, Me; R o-anisyl, R' = H, Me) and the achiral ligand C5H3N(2-Me)(6-CH2PPh2) toward (COD)Rh+ are reported. The results show that steric hindrance of the 2-position of the pyridyl ring induces a labile character of the Rh-N bond. Moreover, for R = o-anisyl and R' = Me, a dynamic competition for bonding between the N-and O-donating centers is observed. Comparison of the solid state structures of complexes [Rh(COD)(C5H4N(2-CH2PPhMe)][BF4] and [Rh(COD)(C5H3N(2-Me)(6-CH2PPh2)][BF4] shows a significant bond lengthening of the Rh-N bond in the latter complex, consistent with its fluxional behavior observed in solution.
