Synthesis and herbicidal activities of a series of di(aminopyrazoly) ketone derivatives

摘要

In order to obtain new lead compounds with high herbicidal activity, a series of 5-amino pyrazole derivatives were designed and synthesized using a series of relational synthons. Their structures were determined by IR, H-1 NMR, and elemental analyses. These compounds were screened for herbicidal activities against rape and barnyard grass. Their structure-activity relationships are discussed.
