PMR spectra ard structure of 3,4- and 2,5-disubstituted sulfolanes

Conclusions Based on studies of the PMR spectra of 3,4- and 2,5-disubstituted sulfolanes it has been shown that the difference in the chemical shifts of the geminal protons and the values of the chemical shifts of the protons associated with substituents are reliable criteria for establishing the configuration of the disubstituted five-membered cyclic compounds.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1029–1033, May, 1980.The authors would like to thank U. M. Dzhemilev for donating the 2,5-divinylsulfolanes for investigation.
