Patent number: 5639763
Abstract: Compounds of the following structure, the corresponding N-oxides and agriculturally acceptable salts, are disclosed as effective insecticides: ##STR1## in which U is selected from --(CH.sub.2).sub.n -- and ethylidene; Q is selected from hydrogen, hydroxy, sulfhydryl, and fluorine; R is ##STR2## in which V is selected from hydrogen, halogen, alkyl, haloalkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsilyloxy, dialkylamino, cyano, nitro, hydroxy, and phenyl; Y and Z are independently selected from hydrogen and alkoxy; W and X taken together is --OCH.sub.2 CH.sub.2 O--, --CH.sub.2 C(CH.sub.3).sub.2 O--, --OC(CH.sub.3).sub.2 O--, or --N.dbd.C(C.sub.2 H.sub.5)O--; R.sup.1 and R.sup.2 are independently selected from phenyl substituted with halogen, alkyl, haloalkyl, haloalkoxy, alkoxyalkyl, hydroxy, arylthio, alkoxy, dialkylamino, dialkylaminosulfonyl, hydroxyalkylaminocarbonyl, alkylsulfonyloxy, and haloalkylsulfonyloxy; and n is 1, 2, or 3.

Patent number: 5639753
Abstract: This invention relates to pteridine and 8-deazapteridine compounds and compositions containing the same which are useful for controlling insects in agricultural crops. These pteridines may be represented by the following structure: ##STR1## wherein R and R.sup.1 are independently selected from amino, lower alkylamino, di(lower alkyl)amino (e.g., --N(CH.sub.3).sub.2), or di(lower alkyl)aminomethyleneamino (e.g., --N.dbd.CHN(CH.sub.3).sub.2);R.sup.2 is hydrogen, amino, lower alkyl (e.g., --CH.sub.3, --CH(CH.sub.3).sub.2), di(lower alkyl)aminomethyleneamino, hydroxy, lower alkoxy, phenyl or substituted phenyl, haloalkylphenylalkyl (e.g., 3-trifluoromethylphenylmethyl);Q is N or CH;R.sup.3 is -(n).sub.m -R.sup.4, where m is 0 or 1; wherein, when m is 1,n is a bridging atom or moiety selected from oxygen, sulfur, sulfinyl, sulfonyl, lower alkylene (e.g., --CH.sub.2 --, or --CH.sub.2 CH.sub.2 --), lower alkenylene (e.g., --CH.dbd.CH--), lower alkynylene (e.g., --C.tbd.C--), lower haloalkenylene (e.g., --C(Cl).dbd.
