A total of eleven new 1-(1-methoxy-1-ferrocenyl-3-arylpropan-2-yl)-1H-1,2,4-triazole derivatives have been synthesized from acetylferrocene. The structures of the title compounds have been determined by elemental analysis, 1H-NMR and single crystal X-ray diffraction analysis. Bioassay showed that some of the title compounds had high plant-growth regulatory activity.
