| abstract |
The invention concerns phenylacetic acid derivatives of formula (I), in which the variables have the following meanings: X = NOCH3, CHOCH3 or CHCH3; Y = O or NZ, Z standing for hydrogen or alkyl; R1 = H or alkyl; R2 = cyano, nitro, trifluoromethyl, halogen, alkyl or alkoxy; m = 0, 1 or 2, wherein the group R2 can be different when m = 2; R3 = H, cyano, alkyl, alkyl halide, alkoxy or cyclopropyl; R4 = alkylenedioxy, the alkylene groups being partially or completely halogenated, or one of the groups: -(C=O)-Ra, -C(=NORa)-Ap-Rb, -NRc-(C=O)-Ap-Ra, -O-(C=O)-NRaRb or -N(Rc)-ORd, Ra, Rb, independently of each other, being H or optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, heterocyclyl, aryl or heteroaryl; Rc, Rd, independently of each other, being H or optionally substituted alkyl, alkenyl, alkinyl, alkylcarbonyl, alkenylcarbonyl, alkinylcarbonyl, alkoxycarbonyl, alkenyloxycarbonyl, alkinyloxycarbonyl, cycloalkyl, cycloalkylcarbonyl, cycloalkyloxycarbonyl, arylcarbonyl or heteroarylcarbonyl; p = 0 or 1; A = O, S or N, the N-atom carrying H or alkyl; n = 1 or 2, wherein the group R4 can be different when n = 2; and R5 = H, alkylsulphonyl or optionally substituted alkyl, alkenyl, alkinyl or cycloalkyl. The invention further concerns salts of these substances, a process and intermediate products for their preparation, and their use as fungicides and pesticides. |
