Insecticidal cyclopropane carboxylates

摘要

Novel cyclopropane carboxylates in all isomeric forms of the formula <IMAGE> I wherein A is selected from the group consisting of -O-, -S-, <IMAGE> and -SO2-, R1 is selected from the group consisting of optionally unsaturated alkyl of 1 to 18 carbon atoms optionally containing at least one heteroatom in the carbon chain and optionally substituted with at least one halogen, aryl of 6 to 18 carbon atoms and aralkyl of 7 to 18 carbon atoms and R2 is selected from the group consisting of hydrogen, optionally unsaturated alkyl of 1 to 12 carbon atoms, optionally unsaturated cycloalkyl of 3 to 12 carbon atoms and residue of other alcohols used in pyrethrinoids having pesticidal activity for combatting insects, acariens of vegetables and warm-blooded animals and nematodes and novel intermediates.
