This invention provides novel insecticidally and acaricidally active pyrimidine derivatives of formula (I): ##STR1## and stereoisomers thereof, wherein R.sup.1 is selected from alkyl; alkenyl; alkynyl; haloalkyl; haloalkenyl; and cycloalkyl optionally substituted by alkyl or halogen; R.sup.2 is selected from alkyl; haloalkyl; alkoxy; alkylamino; dialkylamino; halogen; cycloalkyl optionally substituted by halogen or alkyl; and phenyl optionally substituted by alkyl, haloalkyl, halogen or alkoxy; R.sup.3 is selected from hydrogen and halogen; R.sup.4 is the residue of an alcohol of formula R.sup.4 --OH which forms an insecticidal ester when combined with chrysanthemic acid, permethrin acid or cyhalothrin acid; and X is selected from oxygen and sulphur.

This invention provides novel insecticidally and acaricidally active pyrimidine derivatives of formula (I):
and stereoisomers thereof, wherein
R' is selected from alkyl; alkenyl; alkynyl: haloalkyl; haloalkenyl; and cycloalkyl optionally substituted by alkyl or halogen;R2 is selected from alkyl; haloalkyl; alkoxy; alkylamino; dialkylamino; halogen; cycloalkyl optionally substituted by halogen or alkyl; and phenyl optionally substituted by alkyl, haloalkyl, halogen or alkoxy;R3 is selected from hydrogen and halogen;R4 is the residue of an alcohol of formula R4-OH which forms an insecticidal ester when combined with chrysanthemic acid, permethrin acid or cyhalothrin acid; andX is selected from oxygen and sulphur; provided that R2 may not represent an alpha-branched alkyl group or a cycloalkyl group when R' represents 1-methylethyl.
