Abstract

It has been shown by IR spectroscopy that the equatorial oxygen atoms of cholestanol and its methyl ether possess a greater capacity for forming H bonds as proton acceptors than the axial atoms of the corresponding epimeric compounds. The constants of the equilibrium phenol + ether ⇄ H-complex (1:1) in CCl4 at room temperature are 13 and 7 liter/mole, respectively, for the methyl esters of cholestanol and of epicholestanol.
