Ionic Liquids Catalyzed Friedel–Crafts Alkylation of Substituted Benzenes with CCl4 Toward Trichloromethylarenes

Abstract: An ionic liquid catalyzed Friedel–Crafts alkylation reaction of substituted benzenes with CCl4 was developed. The reaction proceeded efficiently under mild conditions, gave corresponding trichloromethylarenes with diversity functional groups in moderate to good yields. The influence of Lewis acidity of ionic liquids on the conversion of the alkylation reaction has been investigated. Notably, the probable mechanism of this reaction has been proposed with the assistance of 27Al NMR spectroscopy. It was noteworthy that the predominance of [Al2Cl7]? species in EmimCl–AlCl3, N = 0.67 could be detected by 27Al NMR spectral analysis, and [AlCl4]? was generated at the beginning of reaction. Additionally, it was found that [AlCl4]? could be transformed into [Al2Cl7]? when the reaction finished. Some control experiments confirmed that the interaction between Lewis acidic species [Al2Cl7]? of the ionic liquid and CCl4 led to the change in speciation of aluminum during the alkylation reactions.

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.
