title: Condensation of some substituted salicylaldehydes with hydrazine.
abstract: Hydrazones and azines of 5-chloro-, 5-bromo-, 3,5-di-iodo-, 5-nitro- and 3-nitro salicylaldehydes have been prepared by condensation with hydrazine. They have been characterized by their melting points, solubilities, elemental analysis and infrared spectra. Ambiguous literature on some of the compounds has also been clarified. Conditions for smooth condensation have been worked out. The extent of the condensation is found to depend on the nature of the substituent group in the salicylaldehydes.
