    Abstract: The invention comprises reaction products (half-esters) of dicarboxylic or tetracarboxylic anhydrides and ureas of the formula where R is methyl, methoxy or isobutinyl, each X is hydrogen, halogen or C1- 4 alkyl and n is 1 or 2. Specified anhydrides are those of succinic, maleic, citraconic, glutaric, phthalic, pyromellitic, naphthalic and diphenic acids; and of hydrogenated, chlorinated and/or nitrated phthalic acids, chlorinated succinic acid, mono- and dichloromaleic acid, and chlorinated and/or nitrated naphthalic and diphenic acids. These compounds are herbicides (see Division A5).ALSO:Agents for controlling unwanted vegetation are reaction products of dicarboxylic or tetracarboxylic anhydrides with ureas of the formula where R is methyl, methoxy or isobutinyl, each X is hydrogen, halogen or C1-4 alkyl, and n is 1 or 2, (see Division C2), together with a liquid or solid carrier. The active compounds may be used in the form of salts. The compositions may also contain emulsifiers and/or dispersing agents, and other active ingredients such as urea derivatives, carbamates, halogenated fatty acids, triazines, uracils or boron and arsenic derivatives.

    Abstract: The invention comprises compounds of the general formula and salts and molecular or addition compounds thereof, in which R1 denotes a cyclalkyl radical with more than 6 annular carbon atoms or a tridecyl or alkyl-phenyl radical, R2, R3, R4 and R5 may be identical or different, each denoting an unsubstituted or substituted methylene radical, the substituents being one or two methyl and/or ethyl and/or phenyl groups, with the proviso that, when R1 represents a tridecyl or an alkyl-phenyl radical, at least one of the radicals R2, R3, R4 and R5 is a substitute methylene radical as defined above. The compounds may be prepared by (a) reaction of primary amines or alkanolamines with alkylene oxides to form dialkanolamines which are then cyclised by treatment with dehydrating agents, (b) hydrogenating amination of ketones with primary amino alcohols to form N-substituted alkanolamines which are then reacted with alkylene oxides and cyclised as described above, or (c) reaction of unsubstituted or substituted 2,21-dichloroalkyl ethers with primary amines in the presence of acid-binding agents. The morpholine salts may be prepared by mixing the initial materials, optionally in the presence of solvents, or by treatment of N-substituted dialkanolamines with thionyl halides. The preparation of N-bis-(2-hydroxypropyl)-tridecylamine is described. Many other compounds of the invention are listed. The compounds are fungicides (see Division A5).ALSO:Fungicidal compositions comprise an inert carrier or diluent and a compound of the general formula or salts, or molecular or addition compounds thereof, wherein R1 denotes a cycloalkyl radical with more than 6 annular carbon atoms or a tridecyl or alkyl-phenyl radical, R2, R3, R4 and R5 may be identical or different, each denoting an unsubstituted or substituted methylene radical, the substituents being one or two methyl and/or ethyl and/or phenyl groups, with the proviso that, where R1 represents a tridecyl or an alkyl-phenyl radical, at least one of the radicals R2, R3, R4 and R5 is a substituted methylene radical as defined above (see Division C2). The compositions may be in the form of (a) dusting powders containing inert pulverulent carriers or diluents, (b) solid or liquid compositions for the production of sprays containing inert dispersing agents, wetting agents, adhesives or emulsifiers, or (c) admixtures with other fungicides and/or insecticides. Examples are given.
