| Abstract: | In order to find novel low toxicity and potent herbicides, ten title compounds were synthesized by the multi-step reaction using 2-chloro-5-(chloromethyl)pyridine or 2-chloro-5-(chloromethyl)thiazole as starting materials. The structures of the target compounds were characterized by IR, 1H NMR, MS spectra and elemental analysis. Preliminary bioassays show that some of the target compounds possess good herbicidal activities against selected weeds at a concerntration of 100 mg/L. |
