Abstract: The 4-perfluoroacetyl-, 4-perfluoromethylthio-, 4-perfluoromethylsulfinyl-, and 4-perfluoromethylsulfonyl-4'-nitrodiphenyl ethers comprise a class of compounds that are highly effective herbicides.

Abstract: Compounds of the formula I ##STR1## in which Z, Z.sub.1, R, m and p are as defined in patent claim 1, can be obtained in a simple and economical manner by a novel process wherein a halide of the formula II ##STR2## is reacted with a substituted or unsubstituted vinylbenzene or vinylnaphthalene derivative in the presence of a base and of certain palladium catalysts, such as palladium acetate. The compounds (I) or functional derivatives preparable therefrom are useful, for example, for the preparation of known dyes or fluorescent brighteners, or can be used directly as fluorescent brighteners or as scintillators.

Abstract: 2-Aryl-1,3-cyclopentanedione compounds and their alkali metal and ammonium salts exhibit outstanding herbicidal and acaricidal activity.

Abstract: Water-soluble dyestuffs are disclosed which, in the form of the free acid, have the formula ##STR1## wherein R.sub.1 is selected from the group consisting of H, alkyl having 1-4carbon atoms, cyanoalkyl having 2-4 carbon atoms, hydroxy alkyl having 2-4 carbon atoms or a sulfuric acid ester of a hydroxy alkyl having 2-4 carbon atoms; R.sub.2 is selected from the group consisting of H, methyl, ethyl, methoxy or ethoxy; R.sub.3 is selected from the group consisting of H, halogen, methyl, ethyl, methoxy, ethoxy, or carbonamido having 1-4 carbon atoms;R.sub.4 is selected from the group consisting of H, methyl, ethyl, methoxy or ethoxy; andR.sub.5 is selected from the group consisting of H, methyl, ethyl, methoxy or ethoxy. These dyestuffs are suitable for dyeing and printing cellulose fiber materials and polyamide fibers according to known methods of applying and fixing fiber-reactive dyestuffs and are distinguished by outstanding fastness properties such as fastness to light, wet processing and acid.
