摘　　要：为了寻找高效低毒的农药,设计、合成了标题化合物,它们的结构经元素分析、IR、1HNMR和MS测试而确定,初步的生物活性测试结果表明,部分标题化合物对稗草茎具有良好的植物生长调节活性。In an attempt to discover novel compounds with high activity and low toxicity,a series of new O,O-dimethyl-2,6-pyridinyl diformyloxy alkyl phosphonates have been designed and synthesized by the reaction of 2,6-pyridinyl diformyloxy chloride with 1-hydroxy-2-alkyl phosphonate,The structures of all new compounds were characterized by elementary analysis,IR,1HNMR and MS spectroscopies.The results of preliminary bioassay indicated that some of the target compounds had obviously promotive action for plant growthagainst stalk of barnyard grass.
