RESUMO
In recent decades, the unique structural attributes and purported insecticidal properties of oximes have garnered increasing attention. A variety of insecticides, encompassing fluxametamide, fluhexafon, and lepimectin, have been synthesized, all of which incorporate oximes. This review endeavors to encapsulate the insecticidal efficacy, structure-activity correlations, and operative mechanisms of oxime-containing compounds. Furthermore, it delves into the conceptual frameworks underpinning the design of innovative oxime-based insecticides, thereby shedding light on prospective advancements in this field.

Selective functionalization of a single sp3 C-F bond of the CF3 group represents an appealing way to generate the pharmaceutically privileged difluoromethylene moiety. Herein, a novel protocol for the C-F bond etherification of trifluoromethylalkenes and phenols is reported. A variety of alkenyl difluoroaryloxy ethers are obtained with good chemoselectivity and functional group tolerance. DFT calculation results and control experiments suggest that metal ion Cs+ might be involved in this defluorooxylation. Furthermore, the desired product exhibits a good insecticidal activity.
