- 3. The compound according to claim 1 in which
- A, B and the carbon atom to which they are bonded represent a C.sub.3 -C.sub.6 -spirocycle which can be monosubstituted or polysubstituted by C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl, C.sub.1 -C.sub.3 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -thioalkyl, fluorine, chlorine or phenyl, or
- A, B and the carbon atom to which they are bonded represent a C.sub.3 -C.sub.6 -spirocycle which is substituted by an alkylenediyl group which is optionally interrupted by one or two oxygen or sulphur atoms or by an alkylenedioxyl or an alkylenedithiooxyl group which, together with the carbon atom to which it is bonded, forms a further five- to seven-membered spirocycle, or
- A, B and the carbon atom to which they are bonded represent a C.sub.3 -C.sub.6 -spirocycle in which two substituents together with the C-atoms to which they are bonded represent a saturated or unsaturated carbocyle which is substituted by alkyl(C.sub.1 -C.sub.3), alkoxy(C.sub.1 -C.sub.3), or fluorine, chlorine or bromine and which is optionally interrupted by oxygen or sulphur atom,
- X represents C.sub.1 -C.sub.4 -alkyl, halogen or C.sub.1 -C.sub.4 -alkoxy,
- Y represents hydrogen, methyl, ethyl, propyl, i-propyl, butyl, i-butyl, fluorine, chlorine, bromine, methoxy, ethoxy or trifluoromethyl,
- Z represents methyl, ethyl, prapyl, i-propyl, butyl, i-butyl, tert.-butyl, fluorine, chlorine, bromine, methoxy or ethoxy, represents 0, 1 or 2.
- 4. The compound according to claim 1, in which
- A, B and the carbon atom to which they are bonded represent a C.sub.3 -C.sub.6 -spirocycle which can be at least monosubstituted or polysubstituted by methyl, ethyl, propyl, isopropyl, butyl, iso-butyl, sec.-butyl, tert,-butyl, cyclohexyl, trifluoromethyl, methoxy, methylthio, fluorine, chlorine or phenyl, or
- A, B and the carbon atom to which they are bonded represent a C.sub.3 -C.sub.6 -spirocycle which is substituted by an alkylenediyl group which is optionally interrupted by an oxygen or sulphur atom or by an alkylenedioxyl group which group, together with the carbon atom to which it is bonded, forms a further five- to seven-membered spirocycle,
- A, B and the carbon atom to which they are bonded represent a C.sub.3 -C.sub.6 -spirocycle in which two substituents together with the carbon atoms to which they are bonded represent a saturated or unsaturated five- or six-membered cycle, which is optionally interrupted by oxygen or sulphur,
- X represents methyl, ethyl, propyl, 2-propyl, fluorine, chlorine, bromine, methoxy or ethoxy,
- Y represents hydrogen, methyl, ethyl, propyl, i-propyl, butyl, i-butyl, tert.-butyl, fluorine, chlorine, bromine, methoxy, ethoxy or tri-fluoromethyl,
