Besides my fascination chemicals that produce horrible biologic effects, I'd be interested to see just how this insecticide was made. Anybody
have any info or a patent?
Edit: was going to attach an image, but I don't know what setup this board uses for posting images and whatnot.

very interesting.
i assume:
reppe process (C2H2 + HCHO + catalyst) for butynediol, hydrogenates to butenediol
calcium adipate can be pyrolized to cyclopentanone. but can this be used to make the cyclopentadiene or is there another/simpler way?
i dont have my pdfs on this comp but it seems cyclohexanone/ol can be oxidized to adipic acid with 30%H2O2/H2WO4 or Cu/NH4VO3/HNO3
just adding fuel to the discussion
