Synthesis and insecticidal evaluation of novel 3-acylaminobenzamides containing heptafluoroisopropyl group

A series of novel 3-acylaminobenzamides containing heptafluoroisopropyl group were synthesized,and their structures were characterized by 1H NMR,ESI-MS and HRMS.Their insecticidal activity indicated that some of the title compounds exhibited moderate to high insecticidal activity against diamondback moth(Plutella xylostella) at 20 mg/L,while compound(8j) showed mortality rate of 100% at the concentration of 4 mg/L.
