  Structure−Activity Relationship Development of Dihaloaryl Triazole Compounds as Insecticides and Acaricides. 1. Phenyl Thiophen-2-yl Triazoles

  摘要：

  An extended lipophilic system that incorporated some key elements of first-gene ration 2,6-dihaloaryl actives, such as 1, demonstrated desirable efficacy against chewing insects as well as sap-feeding insects. These four-ring systems, based on 2, were accessed primarily via Suzuki couplings of halothiophene derivatives with appropriately substituted boronic acids. In particular, phenylthiophene systems that incorporated haloxyether groups, such as those in 3, 4, and 5, had the broadest spectrum of activity across chewing and sap-feeding insect pests. Expansion of this structu re- activity relationship to include compounds with differing substitution patterns on the thiophene-C-ring and aryl-D-rings was undertaken. The synthesis and insecticidal activity of 3-aryl-5-(thiophen-2-yl)-l -methyl1 H-[1,2,4]triazoles will be described.
