| Abstract: | A new approach to determination of the stereochemical structure of bis-selenium-substituted alkenes using experimental 77Se NMR studies and B3LYP/6-311G(d) quantum-chemical calculations is developed. Joint analysis of experimental and calculated data allows assignment of signals in the 77Se NMR spectrum. The method was evaluated taking the model compounds (PhSe)HC=C(SePh)R (R = COOMe, CH2NMe2, CH2OH, Ph) as examples. |
