Abstract
Steroid alcohols are converted to their chloroformate esters by reaction with phosgene in the presence of a base. Replacement of chlorine by fluorine takes place smoothly by treatment with anhydrous thallous fluoride in ethylene glycol dimethyl ether. Significant shifts in the positions of both infrared spectra-carbonyl and carbon-oxygen single bond absorption frequency due to the fluorine are discussed.
