ABSTRACT:
A novel nitroisourea derivative and a process for producing the same, which is an important intermediate for the production of a nitroguanidine derivative having an insecticidal activity, and a process for producing a nitroguanidine derivative having an insecticidal activity using the nitroisourea derivative. The process for producing a nitroguanidine derivative represented by formula (1), effective as an insecticide is shown by reaction scheme (2): ##STR1## wherein R.sub.1 represents an alkyl group having from 1 to 4 carbon atoms or a benzyl group; R.sub.2 represents an alkyl group having from 1 to 4 carbon atoms; R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each independently represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms; and Q represents a 5-membered or 6-membered heterocyclic ring having at least one of the following: a nitrogen atom, an oxygen atom or a sulfur atom, one of the hydrogen atoms being substitutable with a halogen atom.
