Abstract

Cyenopyrafen and its geometric isomer were synthesized by various methods, and the structures were characterized by 1 H NMR. 13 C NMR, IR, elemental analyses and X-ray diffraction analyses. The bioassay tests showed that cyenopyrafen exhibited a higher acaricidal activity than its isomer. Cyenopyrafen can be isomerized from the Z form in the presence of a base.
