Abstract
New S(2)- or N(3)-substituted 2-mercapto-5-(4-pyridyl)-1,3,4-oxadiazoles have been obtained and characterized. The direction of substitution depends on the structure of the initial reactants and the reaction conditions. The synthesis of several thiosemicarbazides has been effected from isonicotinic acid hydrazide.
