Abstract
Adducts containing a six-membered olefinically unsaturated ring having a halogen atom on one of the ethylenic carbon atoms (e.g., 3,5-diketo-4,8-dioxa-12-chlorotricyclo[5.3.2.0.sup.2,6 ]-dodec-11-ene) are formed by heating a dienophile (e.g., maleic anhydride) with a gem-dihalocyclopropane which has at least 4 carbon atoms in the molecule and at least one hydrogen on a carbon atom singly bonded to the cyclopropane ring (e.g., 7,7-dichloro-2-oxabicyclo[4.1.0] heptane). The adducts have toxicological properties and thus may be used as insecticides, fungicides, bactericides, herbicides, miticides and the like. They are also useful in the manufacture of plasticizers, flameproofing agents, water mark detecting agents, waterproofing agents, degreasing solvents, surface active agents, and the like.
