Design, Synthesis, and Structure‐Activity Relationship (SAR) Studies of Ketone‐Isobenzofuranone Hybrid Herbicides

Abstract

) showed promising herbicidal activity. Among these, the o-F substituted compound (20) was the most effective against Chinese amaranth, and the o-Cl substituted compound (23) was the most potent against barnyard grass. This is the first time the herbicidal potential of ketone-isobenzofuranone hybrids has been studied. The discovery of current chemical clues would be beneficial for the development of novel herbicides.
