N-[2-(4,6-二甲氧基嘧啶-2-氧基)苯亚甲基]取代胺类衍生物的合成及除草活性
Synthesis and herbicidal activity of N- [ 2- (4,6-dimethoxypyrimidin -2-yloxy) benzylidene ] substituted amine derivatives
摘要
Abstract
Six title compounds (3a - 3f) were synthesized using 2-hydroxybenzaldehyde as starting material by substitute reaction,addition reaction and elimination reaction. Thereinto,3a -3d were new compounds. All of the synthesized compounds were confirmed by 1H NMR, MS and elemental analysis. The preliminary bioassay results showed that the inhibition rate of synthesized compounds to the Echinochloa crus-galli, Digitaria sanguinalis, Bluegrass ,Amaranthus retroflexus and Chenopodium album reached 80% , except 3f to the E. Crus-galli was 55% at the application rate of 150 g a. I. /hm2. The inhibition rate of some of the compounds to E. Crus-galli,Poa annua,A. Retroflexus or C. Album reached 100% at the application rate of 150 g/hm2.关键词
