The invention relates to a method for synthesizing aryl halide from aryl carboxylic acid as raw material. The method prepares corresponding aryl halide from an aryl carboxylic acid compound and halide MX through substitution reaction in a solvent and in the presence of oxygen, silver catalyst, copper additive and a bidentate nitrogen ligand, wherein M in MX is alkali metal or alk. earth metal, and X is F, Cl, Br or I. Compared with the conventional aryl halide synthesis method, the method has the obvious advantages such as easily available low-cost reaction raw materials including aryl carboxylic acid and MX, small consumption of metal catalyst, little environmental pollution, good tolerance to multiple functional groups on aromatic ring, and high yield. The method can be widely applied to synthesis of drugs, materials and natural products in the industrial field and academia.

On March 31, 1994, Suzuki, Hitomi; Mori, Tadashi published an article.Quality Control of 2-Chloro-4-methyl-1-nitrobenzene The title of the article was Ozone-mediated nitration of chloro- and bromobenzenes and some methyl derivatives with nitrogen dioxide. High ortho-directing trends of the chlorine and bromine substituents. And the article contained the following:

In the presence of ozone, chloro- and bromobenzenes are nitrated smoothly with nitrogen dioxide at low temperatures, giving a mixture of the corresponding nitro derivatives in nearly quant. yield. The nitration products are generally ortho-rich as compared with those obtained by the conventional procedures based on the use of HNO3 or mixed acid. The ortho:para isomer ratios of the products can be reversed from ortho-rich (o:p = 1.14 and 1.09) to para-predominant (o:p = 0.45 and 0.68) simply by altering the initial concentration of the substrate. This enigmatic phenomenon was interpreted in terms of the equilibrium between the monomer and the dimer forms of the cation radical derived from a halobenzene and the difference in their relative reactivity toward nitrogen dioxide. Similar preference for substitution ortho to the halogen substituent was observed with 4-chloro- and 4-bromotoluenes, which concurrently suffer extensive ipso attack by the present reagent system, giving 4-methyl-2-nitrophenol as a common side product. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).Quality Control of 2-Chloro-4-methyl-1-nitrobenzene

Singh, Man published an article in 2011, the title of the article was Effect of trimethylsulphoxonium halide surfactants on consolute solutions of immiscible solvents.Synthetic Route of 5034-06-0 And the article contains the following content:

Consolute solution temperatures (CST) ± 0.01 K and corresponding solubilities of phenol-water mixtures with 0.35 millimol kg-1 trimethylsulfoxonium chloride (TMSOC), trimethylsulfoxonium bromide (TMSOB), and trimethylsulfoxonium iodide (TMSOI) cationic surfactants are reported. The halide surfactants (TMSOX, X = Cl-, Br-, I-) decreased the CST by about 1.73-2.18° with 3-5% less mutual mixing as compared to phenol-water mixtures Three -CH3 (methyl) and the chloride (Cl-), bromide (Br-) and iodide (I-) halide ions of surfactants had developed hydrophobic and hydrophilic interactions, resp. The CST data are as TMSOI > TMSOB > TMSOC with corresponding mutual solubilities as TMSOC > TMSOB > TMSOI, with slightly stronger I–water interaction due to induced potential of a large-sized iodide ion. The hydrophobic interactions mildly dominated with smaller sized Cl- anion with slightly higher mutual solubility Comparatively, consolute solutions with surfactants are obtained at slightly lower temperatures with higher mutual mixing. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Synthetic Route of 5034-06-0

And the article contained the following:

Structure-based macrocyclization of a 6-carboxylic acid indole chemotype has yielded potent and selective finger-loop inhibitors of the hepatitis C virus (HCV) NS5B polymerase. Lead optimization in conjunction with in vivo evaluation in rats identified several compounds showing (i) nanomolar potency in HCV replicon cells, (ii) limited toxicity and off-target activities, and (iii) encouraging preclin. pharmacokinetic profiles characterized by high liver distribution. This effort culminated in the identification of TMC647055 (I), a nonzwitterionic 17-membered-ring macrocycle characterized by high affinity, long polymerase residence time, and broad genotypic coverage. In vitro results of the combination of I with the HCV protease inhibitor TMC435 (simeprevir) supported an evaluation of this combination in patients with regard to virus suppression and resistance emergence. In a phase 1b trial with HCV genotype 1-infected patients, I was considered to be safe and well-tolerated and demonstrated potent antiviral activity, which was further enhanced in a combination study with TMC435. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Application of 5034-06-0
