摘要

5-Phenylpyrimidines of the formula I in which the substituents and the index are as defined below: R¹,R² are hydrogen, alkyl, haloalkyl, cycloalkyl, halocycloalkyl, alkenyl, haloalkenyl, alkynyl or haloalkynyl, and R¹ and R² together with the nitrogen atom to which they are attached may also form a saturated or unsaturated ring which may be interrupted by an ether, thio, sulfoxyl or sulfonyl group and may be substituted by one to four groups R^a and/or R^b; R³ is hydrogen, halogen, cyano, alkyl, haloalkyl, alkoxy, haloalkoxy or alkenyloxy; R⁴ is hydrogen, halogen, cyano, hydroxyl, mercapto, azido, alkyl, alkenyl, alkynyl, haloalkyl, alkoxy, alkenyloxy, alkynyloxy, haloalkoxy, alkylthio, alkenylthio, alkynylthio, haloalkylthio, -ON-CR^aR^b, -CR^c-NOR^a, -NR^cN-CR^aR^b, -NR^aR^b, -NR^cNR^aR^b, -NOR^a, -NR^cC(-NR^c')NR^aR^b, -NR^cC(-O)NR^aR^b, -NR^aC(-O)R^c, -NR^aC(-NOR^c)R^c', -OC(-O)R^c, -C(-NOR^c)NR^aR^b, -CR^c(-NNR^aR^b), -C(-O)NR^aR^b or -C(-O)R^c; in which R^a, R^b and R^c are as defined in the description; X is halogen, alkyl, alkoxy or haloalkyl; and m is an integer from 1 to 5; processes for preparing these compounds, compositions comprising them and their use for controlling harmful fungi are described.
