Abstract

Insecticidal 1,2,3,4-tetrahydro-5-nitro-pyrimidine derivatives of the formula ##STR1## in which n is 0 or 1, A is a direct bond, --(CH.sub.2).sub.m -- or --(CH.sub.2).sub.x --Y--(CH.sub.2).sub.z, m is a number from 1 to 4, x and z each independently is 0, 1 or 2, Y is oxygen, sulphur, --NH-- or ##STR2## R.sup.2 is optionally alkoxycarbonyl-substituted C.sub.1 -C.sub.4 -alkyl, or cyano, hydroxyl or phenyl, and R.sup.1 is halogeno-C.sub.1 -C.sub.4 -alkyl or an optionally substituted radical from the group consisting of phenyl, naphthyl, anthryl, phenanthryl, pyridyl, furyl, thienyl, piperidyl and 1,3-benzodioxolyl, and their acid addition salts.
