A series of new 3-(substituted benzyloxy)-6-(substituted amino)pyridazines were synthesized through the reaction of 3-(substituted benzyloxy)-6-fluoropyridazines with the solution of dimethylamine in absolute ethanol in a sealed tube in 75～80 ℃ or with morpholine or piperidine under reflux, respectively. The title compounds were identified by IR, 1H NMR spectra and elemental analyses. Preliminary bioassay showed that some of them had certain extent herbicidal activities, and the structure-activity relationship was also discussed.

Key words: synthesis, herbicidal activity, structure- activity relationship, 3-(substituted benzyloxy)-6-(substituted amino)pyridazine
