title: Synthesis of new derivatives of 3-benzyl-4-R-delta 2-1,2,4-triazolin-5-one and 3,3'-methylidyne bis(4-R-1,2,4-delta 2-triazolin-5-one).
abstract: In the reaction of phenylacetic acid hydrazide or malonic acid hydrazide with isocyanates, new derivatives of semicarbazide were obtained [I-VIII]. Cyclization of these derivatives with a aqueous 2% sodium hydroxide led to the formation of new derivatives of delta 2-1,2,4-triazolin-5-one [IX-XVI]. Some of them were investigated pharmacologically on the central nervous system in mice.
