ABSTRACT:
Phosphoro-thioates or dithioates of the formula (I), ##STR1## wherein R is a C.sub.1 -C.sub.3 alkyl group, R.sub.1 is a C.sub.1 -C.sub.3 alkoxy, C.sub.1 -C.sub.4 alkylamino or allylamino group, R.sub.2 is a halogen atom, a C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.3 alkyl group, R.sub.3 is a hydrogen or halogen atom or a C.sub.1 -C.sub.3 alkyl group, R.sub.4 is a C.sub.1 -C.sub.3 alkyl group, and X is an oxygen or sulfur atom, provided that when R.sub.1 is a C.sub.1 -C.sub.4 alkylamino or allylamino group, X is an oxygen atom, a process for producing phosphoro-thioates or dithioates of the formula (I) characterized by condensing a pyrimidine of the formula (II), ##STR2## wherein Y is a halogen atom, and R.sub.2, R.sub.3 and R.sub.4 are as defined above, with a thio- or dithio-phosphate of the formula, ##STR3## wherein M is an alkali metal atom or an ammonium group, and R, R.sub.1 and X are as defined above, an insecticide, acaricide and nematocide characterized by containing phosphoro-thioates or dithioates of the formula (I) as an active ingredient, and pyrimidines, novel intermediate compounds, of the formula (II) wherein R.sub.2 is a C.sub.1 -C.sub.4 alkoxy group or a halogen atom, R.sub.3 is a hydrogen or halogen atom or a C.sub.1 -C.sub.3 alkyl group, and R.sub.4 is a C.sub.2 -C.sub.3 alkyl group.
