Summary:The photochemical reactions of the prototype compound (2E,4E)-N-isobutyl-6-phenylhexa-2,4-dienamide are examined as a first step in understanding the environmental degradation of a potentially important class of insecticides. The reaction rate in aerated methanol irradiated at 310 and 360 nm is similar to that of cypermethrin, a relatively photostable pyrethroid insecticide. The predominant process on direct or sensitized photolysis is E/Z isomerization with the isomer ratio at equilibrium being 2E,4E > 2Z,4E > 2E,4Z > 2Z,4Z.
