  Synthesis and Characterization of CO2-Bridged Ruthenium-Zirconium and Rhenium-Zirconium Complexes

  摘要：

  The synthesis and characterization of the CO2-bridged complexes Cp*Ru(CO)(2)(CO2)Zr-(X)Cp(2) (2a, 3a, 5a; X = Cl, Me, SnPh(3)), Cp*Re(CO)(NO)(CO2)Zr(X)Cp(2) (2b, 3b, 5b; X = CI, Me, SnPh(3)), and Cp*Ru(CO)(2)(CO2)SnPh(3) (4) are described. Compounds 2a,b have been structurally characterized. The geometry about the zirconium atom in 2a,b is edge-capped tetrahedral, All compounds have been characterized by solid-state IR data; comparisons of these data with those from other symmetrical mu(2)-eta(3)-CO2 compounds show that, although v(asym) for the CO2 ligand varies slightly with the metallocarboxylate fragment, it is highly dependent upon the coordination geometry of the metal center which binds the two carboxyl oxygens.

  Preparation and characterization of the rhenium silyl esters (η5-C5Me5)(CO)(NO)ReC(O)OSiR3 (SiR3 = SiMe2Ph, SiEt3)

  摘要：

  Three synthetic approaches to the rhenium silyl esters Cp*(CO)(NO)ReC(O)OSiEt3 (3) and Cp*(CO)(NO)ReC(O)OSiMe2Ph (4) were evaluated. (a) Treatment of a CH2Cl2 solution of Cp*(CO)(2)(NO)Re+BF4- with a silanolate NaOSiEt3 (5) or NaOSiMe2Ph (6) provided 90% isolated yields of 3 and 4. These stable orange-yellow solids an extremely moisture sensitive: traces of water hydrolyze them to Cp*(CO)(NO)ReCO2H and the parent silanol. IR and NMR spectral data of 3 and 4 are consistent with nonchelating mu(eta(1)-C:eta(1)-O) metalloester structures. Less efficient preparative routes to 3 and 4 include treatment of (b) Cp*(CO)(NO)ReCO2H with the requisite chloroalkylsilane and (NPr2Et)-Pr-i, and (c) Cp*(CO)(NO)ReCO2-Na+ (7Na(+)) with the chloroalkylsilane. The new rhenium CO2 adducts Cp*(CO)(NO)ReCO2-M+ (7Li(+), 7Na(+)) were generated by deprotonation of Cp*(CO)(NO)ReCO2H with excess LIH or NaH THF suspensions at 0 degrees C. Both 7Li(+) and 7Na(+) were characterized by their solution IR spectra and by the formation of their derivatives with silyl and tin chlorides.
