title: Synthesis of new derivatives of bis-3(4-R-delta2-1,2,4-triazolin-5-one).
abstract: In the reaction of oxalic acid hydrazide with isocyanates, new derivatives of semicarbazide were obtained [I-XII]. Cyclization of these derivatives with an aqueous 2% sodium hydroxide led to formation of new derivatives of delta2-1,2,4-triazolin-5-one [XIII-XXIV].
