On January 11, 2018, Su, Ji; Chen, Qian; Lu, Le; Ma, Yuan; Auyoung, George Hong Lok; Hua, Ruimao published an article.SDS of cas: 321-28-8 The title of the article was Base-promoted nucleophilic fluoroarenes substitution of C-F bonds. And the article contained the following:

With the use of KOH/DMSO as the superbase medium, the nucleophilic fluoroarene substitution for C-F bonds was presented. The transformation proceeds smoothly with the use of fluoroarenes such as 2-fluoro-benzamide, 3-fluorobenzaldehyde, 3,4-difluoronitrobenzene, etc. bearing not only electron-withdrawing group, but also electron-donating group and a variety of nucleophiles such as methanol, phenol, dimethylamine, 1H-pyrrole, benzamide, etc.. The double nucleophilic substitution using 3,4-difluoronitrobenzene and nucleophiles bearing ortho-dinucleophilic groups such as 1,2-ethanediol, 1,2-benzenediol, 2-amino-phenol results in the formation of 6-Nitro-2,3-dihydrobenzo[b][1,4]dioxine, 2-Nitrodibenzo[b,e][1,4]dioxine and 2-Nitro-10H-phenoxazine in moderate to good yields.

Zhao, Feng; Tan, Qi; Wang, Dahan; Deng, Guo-Jun published an article in 2020, the title of the article was Metal- and solvent-free direct C-H thiolation of aromatic compounds with sulfonyl chlorides.Quality Control of 2-Methoxynaphthalene And the article contains the following content:

A simple, efficient and green method for the direct thiolation of aromatic compounds using com. available sulfonyl chlorides as the sulfur source was developed under metal- and solvent-free conditions. The C-S bond was constructed via direct C-H functionalization of diverse aromatic compounds under an oxygen atm. In this process, various diaryl sulfides were synthesized in moderate to excellent yields. This protocol shows a broad substrate scope and good functional group tolerance. Moreover, a gram-scale experiment was also conducted to prove the prospect of this method for the scale-up synthesis of diaryl sulfides. Mechanistic studies indicate that this procedure probably undergoes a radical pathway.

On October 1, 2021, Li, Xue; Bai, Fang; Liu, Chaogan; Ma, Xiaowei; Gu, Chengzhi; Dai, Bin published an article.Safety of 2-Methylanisole The title of the article was Selective Electrochemical Oxygenation of Alkylarenes to Carbonyls. And the article contained the following:

An efficient electrochem. method for benzylic C(sp3)-H bond oxidation has been developed. A variety of methylarenes, e.g., p-chlorotoluene, methylheteroarenes, e.g., 6-methylquinoline and benzylic (hetero)methylenes, e.g., p-ethyltoluene could be converted into the desired aryl aldehydes, e.g., 4-chlorobenzaldehyde/e.g., quinoline-6-carbaldehyde and aryl ketones, e.g., 1-(p-tolyl)ethan-1-one in moderate to excellent yields in an undivided cell, using O2 as the oxygen source and lutidinium perchlorate as an electrolyte. On the basis of cyclic voltammetry studies, 18O labeling experiments, and radical trapping experiments, a possible single-electron transfer mechanism has been proposed for the electrooxidation reaction.
