| titleOfInvention | Process for the preparation of pyrethrins and analogues thereof and insecticidal compositions containing the same |
| abstract | Abstract of the Disclosure The invention relates to a new process for the preparation of optically active or racemic pyrethrin compounds of general formula I (I ) (wherein R11 is a straight or branched chain lower alkyl group or 1-alkenyl group or hydrogen; R and R12 may be the same or different and stand for hydrogen, halogen or lower alkyl or one of the symbols R and R12 may also stand for lower alkoxy-carbonyl; the ? valency bond represents .alpha.- and/or .beta.-configuration; the - valency bond represents .beta. -configuration). The compounds are prepared by subjecting an optically active or racemic chrysanthemic ester derivative of formula II (wherein R11, R and R12, ? and - have the meanings given above) to oxidation by treatment with an oxidizing agent in an aprotic or inert organic solvent The pyrethrin compounds of formula I are valuable insecticides. |
