【Abstract】 Fifteen new N-5-(1H-1,2,4-triazolyl)-N′-arylformyl ureas have been synthesized by the reaction of 5-amino-1H-1,2,4-triazol-3-carboxylic acid with arylacyl isocyanate. Their structures were determined by 1H NMR, IR spectra and elemental analysis. The biological activity tests show that some target compounds have a good activity as plant growth regulator, and N-5-(3-carboxy-1H-1,2,4-triazolyl)-N′-o-chlorophenylformyl urea, N-5-(3-carboxy-1H- 1,2,4-triazolyl)-N′-o-bromophenylformyl urea, N-5-(3-carboxy-1H- 1,2,4-triazolyl)-N′-p-(or m-)methyl-phenyl formyl urea have excellent activity of auxin.更多还原
