| Abstract: | Conclusions From an analysis of the variation of1 H NMR spectra with temperature it has been shown that 2-substituted 5,6-benz-1,3-dithiepins exist in solution in the chair-e and boat-e conformations, the equilibrium between which depends considerably on the nature of the solvent.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 545–548, March, 1987.The authors wish to thank E. N. Klimovitskii and D. Yu. Strel'nik for submitting compound (III). |
