| Abstract: | A series of 3-arylalkylamino-6-chloropyridazines have been synthesized by the condensation of 3,6-dichloropyridazine with (un)substituted arylalkylamines in N,N-dimethylformamide (DMF) catalyzed by NaH at 120～130 ℃ or n-BuOH under reflux, and confirmed by 1H NMR, IR spectra and elemental analyses. Preliminary bioassay showed that some of them have certain herbicidal activity against broad leaf grasses, for example, at the dosage of 10 µg•mL－1, the inhibition percentage of compound 4f against Brassica napus reached 76.42%. Moreover, the structure-activity relationship was discussed. |
