摘要

In order to search for novel agrochemicals with high activity and low toxicity,a series of phosphonate derivatives containing 1,2,3-triazole and thiazole rings were designed and synthesized using 2-chloro-5-(chloromethyl)thiazole as the starting material.Their structures were confirmed by IR,1H NMR,31P NMR,EI-MS or ESI-MS and elemental analyses.The crystal structure of 7a was determined by single crystal X-ray diffraction.Prelimihary bioassays indicated that most of the target compounds did not display insecticidal activities,but a fraction of them possessed herbicidal and fungicidal activities to some extent.
