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.
这项发明提供了化学式为:##STR1##的杀虫活性化合物,其中X为N或CH;R.sup.a为(R.sup.1)(R.sup.2)NS(O).sub.n的基团--其中R.sup.1和R.sup.2分别独立选择自H、烷基、卤代烷基、烷氧基、烷氧基烷基、甲酰基、烷酰基、烯基、炔基、可选取代的环烷基、可选取代的环烷基甲基、可选取代的苄基和可选取代的苯基,n为0、1或2;R.sup.b为--OSO.sub.2 R.sup.3的基团,其中R.sup.3为烷基,可选取代为可选取代的苯基基团、卤代烷基、可选取代为可选取代的苯基基团的烯基、可选取代的芳基或N(R.sup.4)(R.sup.5),其中R.sup.4和R.sup.5分别独立选择自H和烷基;R.sup.a和R.sup.b基团在X为CH时相对于彼此占据1,3构型,或在X为N时相对于X占据2,4或2,6构型。这项发明提供了包括这些化合物的杀虫剂组合物,以及在控制昆虫方面使用它们的方法,并提供了制备这些化合物的过程和中间体。
