    Abstract: High molecular weight polyphenylene ethers are prepared from monohydric phenols by an oxidative coupling reaction with oxygen in the presence of a solvent and of a catalyst complex consisting of a copper salt and an organic amine of the general formula where R1 is C2-C20-alkylidene, preferably C2-C12-alkylid-ene, or alkenylidene, R2 is H or C1-C12-alkyl, preferably C1-C4-alkyl, or C5-C8-cycloalkyl, each of which is unsubstituted or substituted by functional groups, and n is an integer from 1 to 4, preferably 1 or 2. Preferred functional groups are -OR3, -NHR3 or -SR3, in which R3 is H C1-C12-alkyl or C5-C8-cycloalkyl, and the most suitable amines are 3-tert.-butoxypropylamine, 4-tert.-butoxy-butylamine, 3-tert.-butoxy-2-methylpropylamine, 3-tert.-butoxy-2,3-dimethylpropylamine, 3-tert.-butoxy-2-methyl-octylamine and N-methyl-N-(4-tert.-butoxybutyl)-amine. The polyphenylene ethers can be processed to moldings by a thermoplastic method.

    Abstract: Cyclohexane-1,3-dione derivatives of the formula I I, where R1 is cycloalkyl of 3 to 12 carbon atoms which may or may not be olefinically monounsaturated to tetraunsaturated, can be substituted by not more than 3 methyl or ethyl groups, one vinyl, methylvinyl or allyl group, 1 or 2 chlorine atoms or one alkoxy group of 1 to 4 carbon atoms and can be bridged by an alkylene chain of not more than 4 carbon atoms, X is alkylene of 1 to 5 carbon atoms, which can be monounsaturated or diunsaturated, interrupted by not more than 2 sulfur or oxygen atoms and substituted by not more than 3 alkyl groups of 1 to 3 carbon atoms, R2 is hydrogen or alkoxycarbonyl where alkoxy is of 1 to 2 carbon atoms, R3 is alkyl of 1 to 4 carbon atoms, R4 is alkyl of 1 to 3 carbon atoms, alkenyl of 3 or 4 carbon atoms, propargyl or haloalkenyl of 3 or 4 carbon atoms and 1 to 3 halogen atoms, and the salts of these compounds, processes for their preparation, herbicides containing these compounds, and their use.
