Abstract: Novel aniline compounds that are useful in preparing N-aroyl N'-phenyl ureas having alkyl substituents in the 2-, 3-, 5- and 6-positions and haloalkoxy in the 4-position of the N'-phenyl which are more active and have a broader spectrum of effectiveness than the known benzoylurea insecticides.

Abstract: N-aroyl N'-phenyl ureas having the formula ##STR1## wherein: Ar is a substituted phenyl, pyridyl or pyrimidinyl radical wherein the substituents are chloro, bromo, fluoro C.sub.1 -C.sub.3 alkyl or C.sub.1 -C.sub.3 alkoxy, with the proviso that at least one substituent is positioned ortho to the carbonyl group; R.sub.3 and R.sub.4 are individually H or C.sub.1 -C.sub.4 alkyl or together they form the group ##STR2## Y is O or S; X.sub.1, X.sub.2, X.sub.3 and X.sub.4 are individually H, halogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, alkylcarbonyl, alkoxycarbonyl, C.sub.1 -C.sub.3 alkylthio, NO.sub.2, CN or NR.sub.5 R.sub.6 wherein R.sub.5 and R.sub.6 are H or C.sub.1 -C.sub.3 alkyl with the provisos that at least one of X.sub.1, X.sub.2, X.sub.3 or X.sub.4 is other than H and (a) when three of X.sub.1, X.sub.2, X.sub.3 or X.sub.4 are H, the fourth substitution cannot be halogen or alkyl, (b) when X.sub.1 and X.sub.3 are H, X.sub.2 and X.sub.4 cannot both be halogen, (c) when X.sub.2 and X.sub.

Abstract: Dihalo and haloalkyl, haloalkoxy or haloalkylthio-substituted anilines and aniline derivatives, e.g. isocyanates that are useful in the preparation of acyl ureas having insecticidal activity.

Abstract: Novel N-aroyl N'-phenyl urea compounds having halogen substituents in the 2- and 5-position of the phenyl radical possess exceptional insecticidal activity.

Abstract: Novel N-aroyl N'-phenyl ureas having halogen substituents in the 3- and 5-positions and haloalkyl, haloalkoxy or haloalkylthio in the 4-position of the N'-phenyl are more active and have a broader spectrum of effectiveness than the known benzoylurea insecticides.

Abstract: Compounds are prepared which correspond to the formula ##STR1## wherein R represents alkyl of 1 to 4 carbon atoms and R.sup.1 represents OR, amino or mono- or dialkylamino wherein each alkyl group is of 1 to 4 carbon atoms. These compounds have been found to be highly active in the kill and control of soil insects.
