precursors [ReN2(P)4Cl] (P = PMe2Ph, 3 and PMePh2, 4) with ligands resulted in interesting dinuclear oxo-(μ-oxo)-Re(V) species [Re2(O)3(Ln)2(P)2] (P = PMe2Ph, n = 1, 13; n = 2, 14; n = 4, 15. P = PMePh2, n = 2, 16). Suitable crystals for an X-ray analysis have been obtained for complex 14. The structure represents one of the few cases where, for steric reasons, the Re–O–Re bridging unit is not linear but rather
KReO 4与苯甲酰肼在浓HCl和PPh 3存在下,得到[Re V(NNC(Ph)O)(PPh 3)2 Cl 2 ] 1,将其与一氧化碳转化为二氮Re(I)络合物[ReN 2(CO)2(PPh 3)2 Cl] 2的产率很高。一类新的配体 通过结合N-保护的N,得到通式为HL n(n = 1-5)的氨基酸 和 苯甲酸 和 2-氨基噻唑。配合物2与HL n反应 ,通过取代N 2 和CO基团得到中性的Re(II)螯合物[Re(L n)(CO)(PPh 3)2 Cl] 5–9(n = 1–5)。配合物9的分子结构通过X射线衍射测定。当[Re(NNC(Ph)O)(PPh 3)2 Cl 2 ] 1与HL n(n = 2,5)以不同的化学计量比进行反应时,中性的单取代和双取代的Re(III)organodiazenido配合物[回复(NNCOPh)(L 2,5)(PPH 3)2 CL] 10,11和[重(NNCOPh)(L
