1. Claims (for the Contracting States : BE, CH, DE, FR, GB, IT, LI, NL) A compound of the formula I see diagramm : EP0144001,P13,F4 in which X denotes O or -CH2 - ; Y denotes O, S or NR**5 ; A denotes a direct bond, -CH2 -CH2 - or -CH=CH- ; R**1 denotes the radical see diagramm : EP0144001,P13,F5 see diagramm : EP0144001,P13,F6 or see diagramm : EP0144001,P13,F7 where Z = CH or N, Q = O or S and n = 0 or 1 ; R**2 denotes (C1 -C4 )-alkyl, where, if Y = NR**5 , R**2 and R**5 , together with the nitrogen atom, can form a 5-membered or 6-membered ring, in which one -CH-group may be replaced by O or NH ; R**3 and R**4 independently of one another denote hydrogen or (C1 -C4 )-alkyl, or together denote the group see diagramm : EP0144001,P14,F1 and, if R**3 = hydrogen, R**4 also denotes the group -CO-R**8 , -COOR**8 or -CO-NHR**8 ; R**5 denotes hydrogen or (C1 -C4 )-alkyl ; R**6 and R**7 independently of one another denote, H, F, Cl, Br, CH3 , CF3 , NO2 or CN ; and R**8 denotes (C1 -C8 )-alkyl, (C3 -C6 )-alkenyl or phenyl, which can be substituted once or twice by halogen, CF3 or (C1 -C4 )-alkyl. 1. Claims (for the Contracting State AT) A process for the preparation of a compound of the formula I see diagramm : EP0144001,P15,F1 in which X denotes O or -CH2 - ; Y denotes O, S or NR**5 ; A denotes a direct bond, -CH2 -CH2 - or -CH=CH- ; R**1 denotes the radical see diagramm : EP0144001,P15,F2 see diagramm : EP0144001,P15,F3 or see diagramm : EP0144001,P15,F4 where Z = CH or N, Q = O or S and n = 0 or 1 ; R**2 denotes (C1 -C4 )-alkyl, where, if Y = NR**5 , R**2 and R**5 , together with the nitrogen atom, can form a 5-membered or 6-membered ring, in which one -CH-group may be replaced by O or NH ; R**3 and R**4 independently of one another denote hydrogen or (C1 -C4 )-alkyl, or together denote the group see diagramm : EP0144001,P15,F5 and, if R**3 = hydrogen, R**4 also denotes the group -CO-R**8 , -COOR**8 or -CO-NHR**8 ; R**5 denotes hydrogen or (C1 -C4 )-alkyl ; R**6 and R**7 independently of one another denote, H, F, Cl, Br, CH3 , CF3 , NO2 or CN ; and R**8 denotes (C1 -C8 )-alkyl, (C3 -C6 )-alkenyl or phenyl, which can be substituted once or twice by halogen, CF3 or (C1 -C4 )-alkyl, which comprises reacting a compound of the formula see diagramm : EP0144001,P15,F6 in which X, R**1 and A have the abovementioned meaning, and "Hal" is chloro or bromo, with a compound of the general formula see diagramm : EP0144001,P15,F7 in which R**2 , R**3 , R**4 and Y have the abovementioned meaning.
