  • Title: Design, synthesis, and insecticidal activities of novel monohalovinylated pyrethroids.
    Author: Zheng Z, Wang J, Zhang D, Guan X, Gao S, Chen Z, Zou X.
    Journal: J Agric Food Chem; 2011 Feb 23; 59(4):1171-7. PubMed ID: 21275401.
    Abstract:
    A series of novel monohalovinylated pyrethroids are designed and synthesized to replace one halo atom with a hydrogen atom on the double bond of dihalopyrethroids. Bioassays indicate that some of the synthesized compounds, such as 3j and 1j, exhibit high insecticidal activities against mosquitoes ( Culex pipiens pallens ), oriental armyworms ( Mythimna separata ), alfalfa aphids ( Aphis medicagini ), and carmine spider mites ( Tetranychus cinnabarinus ). Photolytic results of E-cis-1j suggest that monohalovinylated pyrethroids are photodegraded more easily than compound 12.
