Synthesis and Herbicidal Activity of Novel Dialkoxyphosphoryl Aryl Methyl 2-(4,6-Dimethoxypyrimidin-2-yloxy) Benzoate Derivatives

A series of dialkoxyphosphoryl aryl methyl 2-(4,6-dimethoxy-pyrimidin-2-yloxy) benzoate derivatives was designed and synthesized. All new compounds were identified by elemental analysis, infrared (IR), 1H-NMR, and mass spectrometry (MS). Their herbicidal activity against a set of weed species was examined. Some of the compounds showed potential herbicidal activity, which provided some indications for further studies on structure modification. Supplemental materials are available for this article.
