Herein, it is reported that meta-selective olefination of fluoroarenes can be achieved via the use of CO2 as a traceless directing group, which can be easily installed and removed in a one-pot process. Furthermore, this approach avoids the use of stoichiometric Ag(I)-salts, commonly used in C-H olefinations, and affords complete meta- over ortho/para-regioselectivity. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Computed Properties of 321-28-8

On September 1, 2021, Toriumi, Naoyuki; Yamashita, Kazuya; Iwasawa, Nobuharu published an article.Recommanded Product: 321-28-8 The title of the article was Metal-Free Photoredox-Catalyzed Hydrodefluorination of Fluoroarenes Utilizing Amide Solvent as Reductant. And the article contained the following:

A metal-free photoredox-catalyzed hydrodefluorination of fluoroarenes was achieved by using N,N,N’,N’-tetramethyl-para-phenylenediamine as a strong photoreduction catalyst. This reaction was applicable not only to electron-rich monofluoroarenes but also to polyfluoroarenes to afford non-fluorinated arenes. The exptl. mechanistic studies indicated that the amide solvent NMP plays an important role for regeneration of the photocatalyst, enabling additive-free photoreduction catalysis. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Recommanded Product: 321-28-8

Tian, Ze-Yu; Zhang, Cheng-Pan published an article in 2022, the title of the article was Visible-light-initiated catalyst-free trifluoromethylselenolation of arylsulfonium salts with [Me4N][SeCF3].Category: ethers-buliding-blocks And the article contains the following content:

The redox potential gap between arylsulfonium salts and [Me4N][SeCF3] has been clearly revealed by CV measurements. Construction of the carbon-selenium bond by overcoming this gap without using catalysts and additives is a challenging task. Here, the authors report an efficient visible-light-induced cross-coupling of arylsulfonium triflates, e.g., 5-[4-(4-cyanophenoxy)phenyl]-5H-thianthren-5-ium triflate, with [Me4N][SeCF3] by simply mixing these two species, which allowed the facile synthesis of various aryl trifluoromethyl selenoethers, e.g., ArSeCF3 (Ar = 2-formyl-4-methoxyphenyl, N-methylcarbazol-6-yl, benzodioxol-5-yl, etc.) under catalyst- and additive-free conditions. The mechanistic study indicated that aryl and SeCF3 radicals might be formed as key intermediates in the reactions. Merits of the reactions include operational simplicity, high efficiency, visible-light irradiation, good functional group tolerance, a wide range of substrates, excellent chemoselectivity, and good yields of (trifluoromethyl)selenolated products, which combined with a sulfenylation process enabled the selective and practical installation of SeCF3 moieties onto complex arenes, including drug mols., via a formal C-H functionalization. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Category: ethers-buliding-blocks

On December 6, 2001, Kido, Junji; Nakada, Hitoshi; Tohma, Teruo; Murayama, Ryuji; Yuki, Toshinao published a patent.COA of Formula: C15H24O2 The title of the patent was Organic electroluminescent display device and chemical compounds for liquid crystals. And the patent contained the following:

The new organic electroluminescent display device has a carrier-transporting layer and/or an organic luminous layer composed of a nematic liquid crystal or a liquid crystal dispersing a carrier-transporting low-mol. therein. When the organic luminous layer is to be bestowed with faculty as a liquid crystal, it is made of a nematic liquid crystal. Both the carrier-transporting layer and the organic luminous layer may be bestowed with faculty as a liquid crystal. Since the liquid crystal is incorporated in the carrier-transporting layer and/or the organic luminous layer, the display device can be driven as a liquid crystal display device in a dark place by charging with a voltage lower than a light emission initiating potential. Of course, it is driven as an electroluminescent display device when it is charged with a voltage higher than the light emission initiating potential. Use of an electroluminescent liquid crystal as an organic luminous layer enables omission of a carrier-transporting layer. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).COA of Formula: C15H24O2
