Abstract: The present invention pertains to new substituted nitrogen heterocycles of general formula (I) ##STR1## in which R.sup.1 and R.sup.2 independently of each other, stand for hydrogen or alkyl,X stands for oxygen, sulfur or an NR.sup.3 group,Y stands for carbon (C or CH) or nitrogen,Z stands for an electron-attracting group,T stands for the remainder of an unsaturated ring system broken possibly by other heteroatoms or heteroatom groups,Q stands for possibly substituted aryl or possibly substituted hetaryl, wherein R.sup.3 stands for hydrogen, alkyl or alkenyl, method for preparing them and their use as pesticides.

Abstract: Insecticidal substituted diazacyclohexanes of the formula ##STR1## in which R.sup.1 is a heterocyclic radical,R.sup.4 is a hydrogen or an organic radical.

Abstract: Insecticidally active substituted aza(cyclo)alkanes of the formula (I) ##STR1## in which R.sup.1 represents a five- or six-membered heterocyclic grouping which contains 1, 2, 3 or 4 nitrogen atoms and/or one or two oxygen atoms or sulphur atoms as the heteroatom ring members--the number of heteroatoms being 1, 2, 3 or 4--and which is optionally substitutedR.sup.2 represents hydroxyalkyl, polyhydroxyalkyl, alkoxyalkyl or polyalkoxyalkyl,R.sup.3 represents hydrogen, alkyl, hydroxyalkyl, dihydroxyalkyl, alkoxyalkyl or dialkoxyalkyl,R.sup.4 represents hydrogen or any of various organic radicals,Y represents nitrogen or a CH group andZ represents cyano or nitro.Also intermediates therefor and process of making.

Abstract: Pesticidal substituted pyridazinones of the formula ##STR1## in which R.sup.1 represents alkyl, halogenolkyl, alkoxyalkyl, alkylthioalkyl, (di)alkylaminoalkyl, alkenyl or halogenoalkenyl, or represents in each case optionally substituted cycloalkyl, cycloalkylalkyl, aryl or aralkyl,R.sup.2 represents halogen or alkyl,R.sup.3 and R.sup.4 independently of one another in each case represent hydrogen or alkyl,R.sup.5 and R.sup.6 represent hydrogen, carboxyl, in each case optionally substituted straight-chain or branched alkyl, alkenyl, alkoxycarbonyl, aryl or aralkyl, or, together with the carbon atom to which they are bonded, rpresent an optionally substituted saturated or unsaturaated carbocyle,R.sup.7, R.sup.8, R.sup.9, R.sup.10 and R.sup.11 independently of one another in each case represent hydrogen, halogen, alkyl, halogenoalkyl, alkoxy, halogenoalkoxy, alkylthio or halogenoalkylthio, andX represents oxygen or sulphur.Several intermediates therefor are also new.
