  Synthesis and characterization of the bromide and hydride derivatives of rhenium(I) 1,2-bis(diphenylphosphinite)ethane complexes

  摘要：

  The reaction of [ReX(CO)(5)] (X=Br, H) with the bidentate phosphinite ligand 1,2-bis(diphenylphosphinite)ethane (L-L), synthesized by reaction of PPh2Cl and ethylene glycol in a 2:1 ratio in the presence of NEt3, at room temperature, affords the mononuclear rhenium(I) complexes fac-[ReBr(CO)(3)(L-L)] (1) and fac-[ReH(CO)(3)(L-L)] (2). The coordination geometry of the complexes was established by diffraction studies and confirmed by spectroscopic data of both complexes. Compound 1 crystallizes in the P2(1)/c (No. 14) monoclinic space group while the hydride complex does so in P2(1) (No. 4). The coordination polyhedron around the rhenium atom in both cases is a slightly distorted octahedron with three carbonyl groups in facial positions. The link of the bidentate ligand to the metal atom leads to a seven-membered ReP2O2C2 ring, adopting a conformation better described as a twisted chair. (C) 1999 Elsevier Science Ltd.

These compounds have been characterized by microanalysis, IR, NMR, mass spectrometry and, in the cases of 1 and 2a, by X-ray diffraction. The metal is in a distorted octahedral

  The previously reported complex [ReBr(CO)(3)L] (L = 1,2-bis[diphenylphosphinite]ethane) was reacted with AgBF4 in dichloromethane to yield fac-[Re(ClCH2Cl)(CO)(3)L][BF4] (1). By contrast, reaction of the same starting material with AgOTf (OTf=OSO2CF3) afforded the neutral complex fac-[Re(OTf)(CO)(3)L] (2). When 2 was treated with NaBArF (BArF=[B3,5-(CF3)(2)C6H3}(4)]) in the same solvent, the complex fac-[Re(ClCH(2)Gl)(CO)(3)L][BArF] (3) was formed. Substitution of the loosely held ligand CH2Cl2 in 1 and 3 resulted in the formation of compounds of the type [Re(X)(CO)(3)L][A] (X = H2O, CH3CN; A = BF4- BArF), whereas the removal of OTf in 2 only was possible to form [Re(NCCH3)(CO)(3)L][OTf]. All the new complexes were characterized by H-1, C-13H-1}, P-31H-1} and F-19H-1} NMR as well as by IR spectroscopies. In the case of compounds 2 and [Re(NCCH3)(CO)(3)L][BF4], X-ray suitable crystals were isolated. In both cases, the Re atom adopts six-coordination by bonding to the three CO ligands, the two P atoms of L and either the oxygen atom of the OTf anion or the N atom of CH3CN. (C) 2004 Elsevier Ltd.
