Abstract

The previously unreported 3-methyltetrahydrothiophene I-oxide (1) and 3-methyl-2, 5-dihydrothiophene I-oxide (2) have been prepared by oxidation of the corresponding sulfides. The structure of these unsymmetric sulfoxides was established by chemical and physical methods. Nuclear magnetic resonance analyses have provided significant information concerning some stereochemical aspects of these molecules. In the case of 1. which has four possible configurations, both cis and trans isomers were shown to exist in the synthetic material. A study on the temperature dependence of the nuclear magnetic resonance spectrum of 2 between -34° and 100°, suggested little or no association of a dimeric nature between molecules of this unsaturated sulfoxide.
