On August 7, 2010, Zhersh, Sergey; Lukin, Oleg; Matvienko, Vitaly; Tolmachev, Andrey published an article.Related Products of 82711-97-5 The title of the article was Synthesis of isomeric fluoronitrobenzene-sulfonyl chlorides. And the article contained the following:

The synthesis of five hitherto unknown isomeric fluoronitrobenzenesulfonyl chlorides is described. The compounds are prepared from difluoronitrobenzenes by a two-step procedure. In the first step the starting compounds undergo a regioselective reaction with phenylmethanethiol giving rise to the corresponding thioethers. The oxidative cleavage of the latter with chlorine results in the sulfonyl chlorides in good yields. One example of a threefold sequential functionalization of 2-fluoro-6-nitrobenzenesulfonyl chloride showing the synthetic utility of the title compounds is provided. The experimental process involved the reaction of 5-Fluoro-2-nitrobenzene-1-sulfonyl chloride(cas: 82711-97-5).Related Products of 82711-97-5

Courtin, Alfred published an article in 1982, the title of the article was Syntheses of sulfonated derivatives of 4-fluoroaniline.Application In Synthesis of 5-Fluoro-2-nitrobenzene-1-sulfonyl chloride And the article contains the following content:

Thermolysis of 4-FC6H4NH2.H2SO4 gave the sulfonated derivative I (R = NH2, R1 = SO3H), the structure of which was confirmed by successive diazotization, chlorosulfonylation, hydrolysis, and Fe-HCl reduction of nitroaniline I (R = NO2, R1 = NH2). Sulfonating acetanilide II (R2 = NHAc, R3 = H) with oleum and hydrolyzing gave benzenesulfonic acid II (R2 = NH2, R3 = SO3H), the structure of which was confirmed by treating II (R2 = NO2, R3 = NH2) analogously to I (R = NO2, R1 = NH2). Sulfonating I (R = NH2, R1 = H) with oleum gave impure II (R2 = NH2, R3 = SO3H). Sulfonating I (R = NO2, R1 = H) with oleum also gave II (R2 = NO2, R3 = SO3H).

Axially chiral biaryls based on pyrene, 1,1′-bipyrene-2,2′-diol derivatives, were designed and synthesized from 2-hydroxypyrene.

Title compounds (I) and corresponding menthylcarbonate (II) showed clear circularly polarized luminescence (CPL) spectra. The degree of dimensionless Kuhn’s anisotropy in the photoexcited state (|gem|) of compounds I and II were ca. 3.6 x 10-4 and ca. 1.2 x 10-3, resp. High fluorescent quantum yields of compounds I and II, 0.57 and 0.80, resp., in marked contrast to that of BINOL, 0.04 and bathochromic shifts of λCPL were noteworthy properties.

On November 5, 2020, Blangetti, Marco; O’Shea, Donal F. published an article.Reference of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate The title of the article was Chiral auxiliary-mediated synthesis of planar chiral [2.2]metacyclophanes. And the article contained the following:

The synthesis of planar chiral [2.2]metacyclophanes, e.g., I was readily accomplished in a single synthetic step via the directed ortho metalation of a pro-chiral substituted metacyclophane. The use of (-)-menthyl chloroformate as a chiral auxiliary allowed the introduction of the useful carbonyl functional group into the aryl ring, giving access to carboxy-substituted diastereomeric mixture of planar chiral [2.2]metacyclophanes. The separation of diastereoisomers was easily accomplished by semipreparative HPLC, allowing the structural anal. of a single diastereoisomer by X-ray crystallog. and NMR spectroscopy. The structural features of the planar chiral metacyclophanes and their high inversion barriers, determined at 473 K, encourage future investigations as chiral catalysts and ligands. This synthetic route complements previously reported enantioselective synthesis by avoiding the restrictive use of (-)-sparteine as the chiral inducer. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Reference of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate

On February 6, 2015, Wallach, Daniel R.; Stege, Patrick C.; Shah, Jigisha P.; Chisholm, John D. published an article.Reference of tert-Butyl trichloroacetimidate The title of the article was Bronsted Acid Catalyzed Monoalkylation of Anilines with Trichloroacetimidates. And the article contained the following:

Trichloroacetimidates are useful alkylating agents for aromatic amines, requiring only a catalytic amount of a Bronsted acid to facilitate the reaction. Monoalkylation predominates under these conditions. E.g., in presence of camphorsulfonic acid in CH2Cl2 at room temperature, monoalkylation of 2,5-dichloroaniline with PhCHMeOC(:NH)CCl3 gave 97% I. Electron-poor anilines provide superior yields, with electron-rich anilines sometimes showing competitive Friedel-Crafts alkylation. A single flask protocol with formation of the imidate in situ is demonstrated, providing a convenient method for the direct substitution of alcs. with anilines. Reaction with a chiral imidate favors a mechanism that proceeds through a carbocation intermediate. The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Reference of tert-Butyl trichloroacetimidate

Ma, Hongpeng; Bai, Chaolumen; Bao, Yong-Sheng published an article in 2019, the title of the article was Heterogeneous Suzuki-Miyaura coupling of heteroaryl ester via chemoselective C(acyl)-O bond activation.COA of Formula: C7H4ClNO4 And the article contains the following content:

A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters RC(O)OR1 (R = naphthalen-1-yl, furan-2-yl, 1H-indol-2-yl, etc.; R1 = pyridin-2-yl, pyrazin-2-yl, 4-methylquinolin-2-yl, etc.) and arylboronic acids R2B(OH)2 (R2 = Ph, 2H-1,3-benzodioxol-5-yl, 4-phenoxyphenyl, etc.) as coupling partners was developed. This methodol. provides a heterogeneous catalytic route for aryl ketones RC(O)R2 formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS anal. of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd0/PdII catalytic cycle that began with Pd0. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).COA of Formula: C7H4ClNO4
