Abstract
4-N,N-Dimethylcarbamoyloxy-6-aminopyrimidines, and salts thereof, of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are each hydrogen, C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -haloalkyl, C.sub.3 -C.sub.6 -cycloalkyl, C.sub.2 -C.sub.5 -alkenyl or C.sub.2 -C.sub.5 -alkynyl, or together they are a C.sub.2 -C.sub.5 -alkylene group, R.sub.3 is halogen or C.sub.1 -C.sub.5 -alkyl, and R.sub.4 is C.sub.1 -C.sub.5 -alkyl, or R.sub.3 is hydrogen and R.sub.4 is C.sub.2 -C.sub.5 -alkyl. There are described a process for producing these pyrimidines, their use for combating pests, and also the intermediates of the formula ##STR2## wherein R.sub.1 and R.sub.2 independently of one another are each hydrogen, C.sub.1 -C.sub.5 -alkyl, C.sub.1 -C.sub.5 -haloalkyl, C.sub.3 -C.sub.6 -cycloalkyl, C.sub.2 -C.sub.5 -alkenyl or C.sub.2 -C.sub.5 -alkynyl, or together they are a C.sub.2 -C.sub.5 -alkylene group, R.sub.3 is halogen or C.sub.1 -C.sub.5 -alkyl, and R.sub.4 is C.sub.1 -C.sub.5 -alkyl, or R.sub.3 is hydrogen and R.sub.4 is C.sub.2 -C.sub.5 -alkyl.
