the anti and syn isomers; the latter rotates incompletely to the more stable isomer upon heating, the equilibrium constant ranging from about 5 to 10 at 150 °C, depending on the solvent. Ionic hydrogenation (deoxygenation) of the 2-(3-methylthienyl) alcohols gives a single product, the syn isomer, in which the methyl group is close to the adamantyls; the anti/syn ratio at equilibrium is substantially
