novel 4‐[(substituted phenoxyacetoxy)methyl]‐2,6,7‐trioxa‐1‐phosphabicyclo[2.2.2]octane‐1‐one 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o were synthesized. Their structures were confirmed by IR, 1H NMR, mass spectroscopy, and elemental analyses. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal and fungicidal activities. For example
一系列新颖的4 [[(取代的苯氧基乙酰氧基)甲基] -2,6,7-三氧杂-1-磷杂环[2.2.2]辛烷-1-酮4a,4b,4c,4d,4e,4f,4g,4h,4I,4J,4K,4升,4米,4N,4O合成。其结构已通过IR确认11 H NMR,质谱和元素分析。初步生物测定的结果表明,某些标题化合物具有中等至良好的除草和杀真菌活性。例如,标题化合物4b,4c,4f,4h,4i和4j在10 mg / L时对油菜和n草根部的生长具有90-100%的抑制作用。此外,标题化合物4f,4g和4h在50 mg / L的浓度下对灰葡萄孢的抑制率为75–89%。
