Synthesis and biological activity of new 1-[4-(substituted)-piperazin-1-ylmethyl]-1H-benzotriazole

Abstract

A new kind of benzotriazole derivatives has been designed and synthesised. The structures of all of the title compounds were characterised by 1 H NMR, IR, MS and elemental analyses. Herbicidal activities of the benzotrizole derivatives were evaluated with barnyard grass and rape cup and KARI tests. The results showed that compounds exhibited weak herbicidal activities against barnyardgrass and rape and KARI enzyme.
