And the article contained the following:

The synthesis and characterization of a novel class of pillar[4]arene[1]thioarenes I [R = Me, Et] was reported. An oxidation-thionation strategy was used to replace a single dialkoxybenzene panel in the parent pillar[5]arene. Spectroscopic(1H NMR) titration experiments, supported by d. functional theory computational studies, revealed that compound I [R = Me] showed starkly modulated host-guest binding properties for electron-deficient aliphatic guests. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Quality Control of 1,4-Dimethoxybenzene

And the article contained the following:

Owing to both Lewis and Bronsted acid active sites on sulfated polyborate under homogeneous conditions, iodination protocol of arenes was developed, which can meet the requirement of regioselectivity and higher yield. The sulfated polyborate activated N-iodosuccinimide for mono iodination of highly activated substrates viz. phenols, anilines under anhydrous condition. Water tuned sulfated polyborate to generate more Bronsted acid sites resulting in rapid activation of NIS for diiodination. The protocol was equally applicable to diiodination of 4-hydroxyphenylacetic acid to synthesize 4-hydroxy-3,5-diiodophenylacetic acid, an intermediate of tiratricol, a thyroid treatment drug. This protocol was further integrated via one-pot sequential iodination and Sonogashira coupling to synthesize aryl acetylenes, building blocks for the synthesis of a variety of specialty chems., API and natural products.

Shigeno, Masanori; Hayashi, Kazutoshi; Korenaga, Toshinobu; Nozawa-Kumada, Kanako; Kondo, Yoshinori published an article in 2022, the title of the article was Organic superbase t-Bu-P4-catalyzed demethylations of methoxyarenes.Related Products of 93-04-9 And the article contains the following content:

The organic superbase t-Bu-P4 catalyzes the demethylation reactions of methoxyarenes ROMe [R = 4-cyanophenyl, 1-oxo-2,3-dihydro-1H-inden-5-yl, 1-benzothiophen-5-yl, etc.] in the presence of alkanethiol and hexamethyldisilazane was reported. The system can efficiently convert a variety of substrates, including electron-deficient, -neutral, and -rich substrates and heteroaromatic substrates, and displays excellent functional group tolerance. Computational studies show that the high reactivity achieved by t-Bu-P4 is due to the formation of the nucleophilic naked thiolate species.
