  Synthesis and Herbicidal Activities of Sodium Methyl(α-(Substituted Phenoxyacetoxy)Alkyl)Phosphinates

  摘要：

  A series of sodium methyl(alpha-(substituted phenoxyacetoxy)alkyl)phosphinates was designed and synthesized. Their structures were confirmed by IR, H-1 NMR and elemental analysis, and some of them were further confirmed by MS. The results of bioassay showed that most of title compounds exhibited moderate to good herbicidal activities against the root of barnyard grass and rape at 10 similar to 100mg/L.

  Synthesis and Biological Activity of α -Oxo-2-Pyridyl Methyl Phosphinates

  摘要：

  In an attempt to discover novel compounds with high activity and low toxicity, a series of new O,O-dimethyl-alpha-(substituted phenoxyacetoxy)-2-pyridyl methyl phosphinates, 5a-5h, have been designed and synthesized by the reaction of substituted phenoxyacetic chloride with 1-hydroxy-2-pyridyl methyl phosphinate, The structures of all new compounds were characterized by elementary analysis, IR, (1)H NMR, and MS spectroscopies. The results of preliminary bioassay indicate that most of the target compounds have excellent inhibitory activities on barnyard grass and rape.
