Abstract: In a new process for the prodn. of aryloxy- or arylthio-substd. aniline derivs. (I), an amino-phenol or amino-thiophenol metal salt (II) is reacted with an aryl halide (III) in the presence of a catalyst and polar aprotic solvents at 80-280 deg.C: One or two CH groups in ring A may be replaced by N-atoms, R1,R2 and R3 are H, halogen, NO2, CN, trihalomethyl, 1-4C alkoxy, 1-4C alkylthio, 1-4C aliphatic, aliphatic sulphonyl or aliphatic sulphoxide residues, or 2-5C carbalkoxy, Q is O or S, X is halogen, and Z is a metal cation. Of the prods. 2'-chloro-4'-trifluoromethyl-3-amino-diphenyl ether, 3'-chloro-4'-trifluoromethyl-3-aminodiphenyl ether, 2'-nitro-4'-trifluoromethyl-3-amino-diphenyl ether, 3,2'-bromo-5'-pyridinoxy-aniline and 2'-chloro-4'-trifluoromethyl- 3-amino-diphenyl thioether are new and claimed. (I) are useful as intermediates for dyes, pharmaceuticals and plant protection agents. Thus, they may be reacted with alkyl isocyanates or alkylcarbamoyl chlorides to give herbicidal urea derivs. or with benzoyl isocyanates to give insecticidal benzoyl-ureas.(I) are also useful as intermediates for pyridazone derivs. with plant growth regulant properties. Simple and economical process gives good yields of highly pure prods. with short reaction times.

Abstract: 1-Haloalkyl isocyanates and 1-alkenyl isocyanates are prepared by reacting 1-haloalkylcarbamic acid halides or 1-haloalkyl isocyanates with alpha -pinene. The 1-alkenyl isocyanates and 1-haloalkyl isocyanates obtained according to the invention are valuable starting materials for the preparation of pest control agents, dyes, drugs, water-repellent textile finishes, detergents, plastics, bleaches and adhesives.

Abstract: Fluorobenzenes of formula (I) are prepd. by reaction of chlorobenzenes of formula (II) with potassium fluoride in a suitable solvent. In the formulae, R1=nitro or cyano and R2=H, an aliphatic radical or halo. The reaction is effected using catalytic quantities of cesium fluoride or when (II) is a m-nitrochlorobenzene or m-cyanochlorobenzene it is not necessary to use cesium fluoride. Suitable solvents are N, N-disubstd. carboxylic acid amides, nitrobenzene, nitriles, aliphatic sulphones and/or aliphatic sulphoxides. (I) are intermediates for dyes, pharmaceuticals and parasiticides. (I) may be reduced to the corresp. aniline deriv. which are used in paints, as germicides and is welding fluxes. Compared with known processes the present process gives higher yields and purer products. The reaction is effected at low temperatures is rapid, economic and suitable for industrial scale prodn.
