A series of 3,5-diaryl-1,2-oxathiolane 2-oxides were obtained in the form of mixtures of the diastereomers as a result of the addition of sulfur dioxide to 1,2-diarylcyclopropanes in the presence of trifluoroacetic acid.The configuration of the 1,2-diarylcyclopropanes and the nature of the substituents have a significant effect on the reaction, which is electrophilic in nature.A possible mechanism for the formation of the 3,5-diaryl-1,2-oxathiolane 2-oxides is proposed.

The reaction of sulfur dioxide with cis-1,2-diphenylcyclopropane and phenylcyclopropane in trifluoroacetic acid at 20 deg C leads to the formation of a mixture of the corresponding isomeric 1,2-oxathiolane 2-oxides.Their structure were established by PMR and (13)C NMR spectroscopy and x-ray crystallographic analysis.
