  摘要：

  Complexation of sulfones (S) with the beta-diketonate Eu(Fod)(3) (Fod-heptafluorodimethyloctanedione) in the ground and excited electronic states in benzene solutions was studied. The stability constants and thermodynamic parameters for the formation of complexes Eu(Fod)(3) . S in the ground state (K, DeltaH(0), DeltaS(0)) and Eu(Fod)*(3) . S in the excited state (K*, DeltaH*(0), DeltaS*(0)) were determined. The excitation of f-f transitions of Eu(III) was found to enhance the stability of Eu(Fod)(3) . S complexes, apparently due to an increase in the acceptor ability of the Eu(III) chelate. This fact confirms the involvement of the 4f orbital in the chemical bond formation. The compensation effect was observed for the thermodynamic parameters: DeltaS(0) = (2.9+/-0.3) x 10(-3) DeltaH(0) + (35.0+/-4.0) in the ground and DeltaS*(0) = (3.3+/-0.3)x 10(-3) DeltaH*(0) + (49.0+/-5.0) in the excited states of Eu(Fod)(3). It was shown that electronic excitation of the 4f orbital of Eu(Fod)(3) influences isotopic effects in complexation with sulfolanes.

  AbstractThe 17O NMR spectra of 3‐alkoxythiolane 1,1‐dioxides indicate that the sulfonyl oxygens are diastereotopic but their chemical shift differences are essentially independent of the structure of the alkyl group in the alkoxy moiety. Eu(fod)3 enhances the 17O chemical shift differences between the diastereotopic sulfonyl oxygens in 3‐isopropoxythiolane 1,1‐dioxide and shifts both oxygens upfield. α,β‐Unsaturation deshields the sulfonyl oxygens in both five‐ and six‐membered rings.
