Their structures were confirmed by elemental analyses, ()~1H NMR and IR spectra. The single crystal structure of 2-[4-(2,4-dichlorophenylmethoxy]phenyl-2-(1,2,4-triazol-1-yl)methane-1,3-dioxolane was determined by means of (X-ray) diffraction. The preliminary bioassays showed that the synthesized compounds exhibited some activities of fungicides and plant growth regulators.展开更多
