oxalyl chloride with DMSO) was shown to dehydrate tertiaryalcohols containing an α-methyl group in the cyclohexanering. Dehydration of equatorial alcohols affords mixtures of isomeric compounds where isomers with an exocyclic double bond dominate, whereas isomers with an endocyclic double bond prevail in the products of dehydration of axial tertiaryalcohols. Thus, Swern’s reagent can serve as a chemical
