Abstract
The invention provides insecticidally active compounds of formula: ##STR1## wherein X is N or CH; R.sup.a is the group (R.sup.1)(R.sup.2)NS(O).sub.n --wherein R.sup.1 and R.sup.2 are independently selected from H, alkyl, haloalkyl, alkoxy, alkoxyalkyl, formyl, alkanoyl, alkenyl, alkynyl, optionally substituted cycloalkyl, optionally substituted cycloalkylmethyl, optionally substituted benzyl and optionally substituted phenyl, and n is 0, 1 or 2; R.sup.b is the group --OSO.sub.2 R.sup.3 wherein R.sup.3 is alkyl optionally substituted by an optionally substituted phenyl group, haloalkyl, alkenyl optionally substituted by an optionally substituted phenyl group, optionally substituted aryl or N(R.sup.4)(R.sup.5), wherein R.sup.4 and R.sup.5 are independently selected from H and alkyl; and wherein the groups R.sup.a and R.sup.b occupy either a 1,3 configuration relative to each other when X is CH, or a 2,4 or 2,6 configuration relative to X when X is N. The invention provides insecticidal compositions comprising these compounds and methods of their use in controlling insects and also provides processes and intermediates for preparing the compounds.
