-
In an attempt to find novel herbicidal compounds,a series of pyrimidiny(thio) ether derivatives was synthesized by nucleophilic substitution of the chlorine at the 4-and 2-positions of 2,4-dichloropyrimidine in turn.The structures of the title compounds were confirmed by elemental analysis,1H NMR and X-ray diffraction methods.The preliminary bioassay results indicate that some of them have herbicidal activity to a certain degree.For example,compounds 7c,7j,7k and 7m exhibit excellent activities against Rape at a dosage of 1×10-4 g/mL(inhibitory ratio 80%).
