Replacement of hydroxyl group in model alcohols by anions applied in form of tetraalkylammonium salts, in presence of diethyl azodicarboxylate and triphenylphosphine was attempted.Benzoylation and phthalimidation of hydroxylic substrates was achieved in this way, whereas iodide or cyanide salts did not enter the reaction.Facile substitution of hydroxyl group by 1,2-diethoxycarbonylhydrazino residue was observed; in the case of menthol the reaction proceeded with retention of configuration.
