(3-Pyridyl)methylidenehydrazides of disubstituted glycolic acids were obtained by the reaction of ethylidenehydrazides of disubstituted glycolic acids with 3-formylpyridine. α-(3-Pyridyl)aralkylhydrazides of disubstituted glycolic acids were obtained by the reaction of the ethyl ester of (3-pyridyl)methylidenehydrazide of oxalic acid or (3-pyridyl)methylidenehydrazides of disubstituted glycolic acids with phenyllithium and alkylmagnesium halides.A correlation was carried out between the pKa values of the compounds obtained and the Taft γ* constants.
