The invention provides insecticidally active compounds of formula (I):
wherein X is nitrogen or carbon bearing a hydrogen atom; R¹ is a group of formula ―S(O)n-Y, wherein Y is an optionally substituted heterocyclic ring containing at least one nitrogen atom, the point of attachment of the group Y being at a ring nitrogen atom, and n is 0, 1 or 2; R² is a group of formula ―OSO₂R³ wherein R³ is selected from C₁₋₈ alkyl, C₁₋₄ alkyl substituted by an optionally substituted phenyl or heterocyclic ring, C₁₋₈ haloalkyl, C₂₋₆ alkenyl, C₂₋₄ alkenyl substituted by an optionally substituted phenyl or heterocyclic ring, C₂₋₄ alkynyl, C₂₋₄ alkynyl substituted by an optionally substituted phenyl or heterocyclic ring, optionally substituted aryl, and a group of formula ―N(R⁴)(R⁵) wherein R⁴ and R⁵ are independently selected from hydrogen and C₁₋₆ alkyl or wherein R⁴ and R⁵ together represent ―(CH₂)p― wherein p is 2, 3, 4 or 5; and wherein the groups R² and R¹ occupy either a 1,3 configuration relative to each other on the ring when X is carbon bearing a hydrogen, or a 2,4 or 2,6 configuration relative to the group X when X is nitrogen.
The invention also provides compositions comprising the compounds of formula (I) and methods of their use in combating insect pests, and novel intermediates and chemical processes for their preparation.
