PMR studies based on lanthanoid shift reagents: aurone and thioaurone steric structures (in Russian)
Journal Article

· Theor. Exp. Chem. (Engl. Transl.); (United States)
The proton resonance spectra have been used along with the interactions with the lanthanoid shift reagent tris-1,1,1,2,2,3,3-heptofluoro-7,7-dimethyloctane-2,6-dione-Eu(III) to establish the isomeric forms and preferred conformations of substituted aurones and thioaurones. Calculations have been performed on the geometrical structures of the LSR-substrate adducts for certain compounds.
