新型七氟异丙基取代2,2-二氟-1,3-苯并二氧-5-乙酰胺衍生物的合成与杀虫活性(英文)

In order to discover novel and environmentally benign pesticides, a series of novel heptafluoroisopropyl substituted 2,2-difluoro-1,3-benzodioxol-5-acetamide derivatives were synthesized via amide condensation reaction in aqueous solution. All the title compouds were characterized by 1H NMR, 19F NMR and HRMS. The bioassays showed that some of the compounds exhibited good insecticidal activities against bean aphids (Aphis craccivora) and armyworms (Mythimna separata). Preliminary structure-activity relationship studies suggested that the substituent groups played a key role in the insecticidal activities of the compounds.
