Uses

Used in Pharmaceutical Industry:
4-Chloro-m-xylene is used as a reagent in the synthesis of 5-aryloxy-2,4-thiazolidinediones, which are potent GPR40 agonists. GPR40 is a G-protein coupled receptor that plays a crucial role in glucose homeostasis and insulin secretion. Agonists of GPR40 have been found to improve insulin sensitivity and lower blood glucose levels, making them potential therapeutic agents for the treatment of type 2 diabetes.
In the synthesis process, 4-chloro-m-xylene serves as a key intermediate, providing the necessary structural elements for the formation of the final product. The chlorine atom in the molecule can be replaced by other functional groups, such as hydroxyl or amino groups, through various chemical reactions, allowing for the creation of a wide range of 5-aryloxy-2,4-thiazolidinedione derivatives with different biological activities and properties.
Furthermore, 4-chloro-m-xylene can also be used as a building block in the synthesis of other pharmaceutical compounds, agrochemicals, and specialty chemicals, owing to its reactive chlorine atom and the presence of the benzene ring with methyl substituents. Its versatility and reactivity make it an important chemical intermediate in various chemical and pharmaceutical processes.

Visible-light photocatalytic activation of N-chlorosuccinimide by organic dyes for the chlorination of arenes and heteroarenes

A variety of arenes and heteroarenes are chlorinated in moderate to excellent yields using N-chlorosuccinimide (NCS) under visible-light activated conditions. A screening of known organic dye photocatalysts resulted in the identification of methylene green as the most efficient catalyst to use with NCS. According to mechanistic studies described within, the reaction is speculated to proceed via a single electron oxidation of NCS utilizing methylene green under visible-light photoredox pathway. The photo-oxidation of NCS amplifies the electrophilicity of the chlorine atom of the NCS, thus leading to enhanced reactivity as a chlorinating reagent with aromatic substrates.

A 3,5-dimethyl aniline method for the preparation of

The invention discloses a preparation method of 3, 5-dimethylaniline. The preparation method is used for preparing the target product 3, 5-dimethylaniline through a reaction of chlorination, nitration and catalytic reductive dechlorination of a ring by taking m-xylene as a raw material. Compared with existing processes, the method disclosed by the invention is few in reaction step and simple in technological process. The yield of 3, 5-dimethylaniline based on m-xylene can reach over 75% of a theoretical amount. The cost of the 3, 5-dimethylaniline can be greatly lowered.

Aromatic substitution in ball mills: Formation of aryl chlorides and bromides using potassium peroxomonosulfate and NaX

Aryl chlorides and bromides are formed from arenes in a ball mill using KHSO5 and NaX (X = Cl, Br) as oxidant and halogen source, respectively. Investigation of the reaction parameters identified operating frequency, milling time, and the number of milling balls as the main influencing variables, as these determine the amount of energy provided to the reaction system. Assessment of liquid-assisted grinding conditions revealed, that the addition of solvents has no advantageous effect in this special case. Preferably activated arenes are halogenated, whereby bromination afforded higher product yields than chlorination. Most often reactions are regio- and chemoselective, since p-substitution was preferred and concurring side-chain oxidation of alkylated arenes by KHSO5 was not observed.

PROCESS FOR HALOGENATION OF BENZENE AND BENZENE DERIVATIVES

In a process of halogenation of benzene or benzene derivatives, di-substituted halobenzene derivatives having para-aromatic compounds or tri-substituted halobenzene derivatives having 1,2,4-substituted aromatic compounds are selectively produced. In halogenation of benzene or benzene derivatives, a fluorine-containing zeolite catalyst such as L-type zeolite, or a zeolite catalyst having the crystal size of at most 100 nm is used. The reaction is preferably effected in the presence of a solvent, and the solvent is preferably a halogenated compound.

Chlorination of aromatic compounds with chlorous acid under non-aqueous conditions

The non-aqueous solution of chlorous acid is a versatile chlorinating agent for aromatic compounds, e.g. alkylbenzenes, anisoles, and acetanililides. It is also an effective chlorine-substitute for the conversion of aryl bromides into aryl chlorides under mild conditions. The stoichiometry of the chlorination reaction is ArH+3HOClO→ArCl+2ClO2+2H2O, and the mode of dissociation of chlorous acid in dichloromethanc is 3HOClO→HOCl+2ClO2+H2O.
