Abstract
Five derivatives of 2-aroylamino-5-(pyrid-3-yl)1,3,4-thiadiazoles IIIa~e have been synthesized by amidation of 2-amino-5-(pyrid-3-yl)-1,3,4-thiadiazoles and substituted benzoyl chloride.The structures of all these compounds were confirmed by ~1H NMR,IR and elementary analysis. It is found from the results of preliminary biological activity tests that IIIc has an excellent auxin activity,whose promoting effect could reach above 40% at the concentration of 10 mg·L~(-1).
