  Rhenium carbonyl complexes with monodentate-coordinated diphosphines: activation of terminal phosphino groups towards amine-oxide oxidation

  摘要：

  Terminal phosphino groups of [Re-2(CO)(9)(eta(1)-P-P)] (P-P = diphosphines) are activated towards oxidation by Me3NO. The respective reactions of MC3NO with [Re-2(CO)(9){eta(1)-P(o-anisyl)(2)(CH2)PPh2}], [Re-2(CO)(9){eta(1)-PPh2(CH2)(3)P(o-anisyl)(2)}] and [Re-2(CO)(9)(eta(1)-trans-PPh2CH=CHPPh2)] were studied to investigate the mechanism of this oxidation. The results are consistent with an intramolecular pathway involving a cyclic intermediate, without exchange of the coordinated and terminal phosphino groups. A mechanism which involves an interaction of the terminal phosphino group with a carbonyl ligand is proposed. In sharp contrast to eq-[Re-2(CO)(9)(eta(1)-P-P)] (P-P = Ph2P(CH2)(n)PPh2, n = 1-6), eq-[Re-2(CO)(9)(eta(1)-trans-PPh2CH=CHPPh2)] appears to be indefinitely stable towards equatorial -> axial isomerization at room temperature, thus, allowing its crystal structure to be determined.
