SYNTHESIS AND BIOLOGICAL-ACTIVITIES OF 1- (SUBSTITUTED PYRAZOL-4-YL)-1,2,4-TRIAZOLES

Twenty three novel heterocyclic compounds with the following general f ormula as follows: R: C6H5, 4-ClC6H4, 4-CH3OC6H4, 4-CH3C6H4, 4-BrC6H4, t-C4H9; R(1): SCH3, NHAr' (Ar': 4-CH3C6H4, 2-CH3OC6H4, 4-ClC6H4); R(2 ): C6H5. have been prepared with alpha-ore-alpha-(1,2,4-triazol-1-yl) ketene dithioacetals as intermediates, and their structures were prove d by elementary analyses and spectral methods. Preliminary bioassay sh ow that some of the,se compounds have plant-regulatory activities.
