| 摘要 |
The present invention relates to new substituted tricyclic compounds of the formula I <IMAGE> in which X stands for O, S, NH, -CH2-, -CHCH3-, -C(CH3)2-, Y stands for O or S, Z stands for O or S, R<1> stands for identical or different radicals from the group comprising hydrogen, halogen, alkyl, alkoxy and haloalkyl, R<2> stands for identical or different radicals from the group comprising hydrogen, halogen, alkyl, alkenyl, haloalkyl, alkoxy, alkylthio, haloalkoxy and haloalkylthio, R<3> stands for hydrogen, alkyl, haloalkyl, alkoxyalkyl, alkenoxyalkyl, alkenyl or alkynyl, R<4> stands for the radicals indicated for R<3>, R<3> and R<4>, together with the adjacent C atoms, can stand for saturated or unsaturated 5- to 7-membered carbocyclic rings, m stands for 1 or 2, n stands for 1 or 2, o stands for 1, 2 or 3 and Het stands for optionally substituted heteroaryl which is not bonded to the other radical via the heteroatom, a process for their preparation and their use for controlling insects, in particular fleas. |
