N-(2-nitrophenyl)-4-aminopyrimidine microbicides

Abstract

The invention relates to novel N-(2-nitrophenyl)-4-aminopyrimidine derivatives of the general formula I ##STR1## wherein R.sub.1 is NO.sub.2 or CF.sub.3, R.sub.2 is NO.sub.2 or CF.sub.3, R.sub.3 is hydrogen or halogen, R.sub.4 is hydrogen or the --C(O)R.sub.7 group, wherein R.sub.7 is C.sub.1 -C.sub.4 alkyl which is unsubstituted or substituted by halogen, C.sub.1 -C.sub.3 alkoxy or C.sub.1 -C.sub.3 alkylthio, R.sub.5 and R.sub.6 are each independently halogen, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkyl which is substituted by halogen or C.sub.1 -C.sub.3 alkoxy, C.sub.1 -C.sub.6 alkoxy which is substituted by halogen or C.sub.1 -C.sub.3 alkoxy, C.sub.1 -C.sub.6 alkylthio or C.sub.1 -C.sub.6 alkylthio which is substituted by halogen or C.sub.1 -C.sub.3 alkoxy, or are C.sub.3 -C.sub.6 cycloalkoxy, C.sub.3 -C.sub.6 cycloalkylthio, C.sub.3 -C.sub.6 alkenyloxy, C.sub.3 -C.sub.6 alkenylthio, C.sub.3 -C.sub.6 alkynyloxy, C.sub.1 -C.sub.6 alkylsulfoxyl, C.sub.1 -C.sub.6 -alkylsulfonyl, C.sub.1 -C.sub.6 alkylsulfonyloxy, C.sub.3 -C.sub.6 alkenylsulfoxyl, C.sub.3 -C.sub.6 alkenylsulfonyl, C.sub.3 -C.sub.6 cycloalkylsulfoxyl or C.sub.3 -C.sub.6 cycloalkylsulfonyl. The invention relates further to methods of preparing these compounds as well as to agrochemical compositions which contain them. Also described is a method of controlling phytopathogenic micro-organisms with the aid of the novel compounds.
