| titleOfInvention | Production of trichloromethyl-substituted phenyl ether compound |
| abstract | PURPOSE: To easily produce the titled compound useful as pharmaceuticals, agricultural chemicals and their intermediates, in high selectivity, yield and purity on an industrial scale at a low cost, by the photo-chlorination of a methyl-substituted phenyl ether. n CONSTITUTION: The objective compound of formula II can be produced by the photo-chlorination of a methyl-substituted phenyl ether of formula I (n is 0 or 1; n=0 corresponds to a bond; two bonds of each benzene ring is not positioned at ortho position on the benzene ring) with chlorine gas at 50W150°C usually for 1W8hr under ultraviolet irradiation with a high-pressure mercury lamp. The starting ether compound of formula I can be easily produced in high yield by reacting an alkali metal salt of m- or p-cresol with p-chlorotoluene or p- or m-dichlorobenzene in the presence of a copper catalyst. n USE: A carboxylic acid and its halide, etc., can be derived from the objective compound and the compound is useful as a raw material for polymer having excellent strength, heat-resistance, etc., such as arylate, wholly aromatic polyamide, etc. n COPYRIGHT: (C)1987,JPO&Japio |
