Substituted arene formyl chloride synthesis method

The invention relates to the technical field of synthesis of fine chemical intermediates, particularly to a substituted arene formyl chloride synthesis method, which comprises: carrying out a reactionon substituted arene formic acid and substituted trichloromethyl arene under the action of a catalyst 3 to obtain the substituted arene formyl chloride. According to the present invention, the synthesis method has characteristics of inexpensive and easily-available raw materials, short process route, good production safety, easy separation of catalyst, high atomic utilization rate, less waste acid discharge, simple post-treatment, high yield and good quality, and is suitable for industrial continuous production.

The preparation method of compound acyl method

The invention relates to the technical field of radiation polymerization curing novel materials, and especially relates to a chemical preparation novel process of an acyl phosphine (oxide) compound represented by the general formula (I). A core characteristic of the method is that: a Grignard reagent of an aromatic compound substituted by an appropriate trichloromethyl group is subjected to condensation with related (substituted) phosphorus halide, such that a critical phosphorus-carbon bond is obtained. The innovativeness, cost economic competitiveness, and environment-friendliness of the process and chemical reaction technology provided by the invention are substantially advantaged than those of literatures and existing process routes.

METHOD FOR PRODUCING SUBSTITUTED ARYLCARBOXYLIC ACID CHLORIDES

The invention relates to a method for producing arylcarboxylic acid chlorides (I) substituted at least once by aryl (C1-C20) and/or halogen consisting, at a first stage thereof, in reacting an aromatic compound (II) substituted at least once by alkyl (C1-C20) and/or halogen with CCl4 in the presence of a Friedel-craft catalyst in such a way that corresponding trichlormethylated aromatic compounds (III) at least once substituted by aryl (C1-C20) and/or halogen are obtainable. At a second stage, the trichlormethylated aromatic compound (III) is treated with water or a proton acid in the presence of a catalyst, whereby making it possible to obtain an arylcarboxylic acid chloride (I). In the preferred embodiment, said trichlormethylated aromatic compound (III) is not isolated in the form of an intermediate product and, at the second stage used dissolved in the solvent of the first stage.
