Some eight-membered sulfites based on diphenylmethane-2,2'-diol and dinaphthylmethane-2,2'-diol were synthesized, and their conformations were studied. In the range of 218-318/sup 0/K the AB quartet of the CH/sub 2/ group in the /sup 1/H NMR spectra of compounds is transformed into two AB quartets, while the spin-spin coupling constants hardly change at all. On the basis of the known criteria and analysis of the line shape it was concluded that there is and equilibrium between the boat-chair forms, having the a and e orientations at the S=O bond.
