Anchimerically Assisted Selective Cleavage of Acid-Labile Aryl Alkyl Ethers by Aluminum Triiodide and N,N-Dimethylformamide Dimethyl Acetal was written by Sang, Dayong;Yue, Huaxin;Zhao, Zhengdong;Yang, Pengtao;Tian, Juan. And the article was included in Journal of Organic Chemistry in 2020.Recommanded Product: 103-16-2 The following contents are mentioned in the article:

Aluminum triiodide is harnessed by N,N-dimethylformamide di-Me acetal (DMF-DMA) for the selective cleavage of ethers via neighboring group participation. Various acid-labile functional groups, including carboxylate, allyl, tert-butyldimethylsilyl (TBS), and tert-butoxycarbonyl (Boc), suffer the conditions intact. The method offers an efficient approach to cleaving catechol monoalkyl ethers and to uncovering phenols from acetal-type protecting groups such as methoxymethyl (MOM), methoxyethoxymethyl (MEM), and tetrahydropyranyl (THP) chemoselectively. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Recommanded Product: 103-16-2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Recommanded Product: 4-Benzyloxyphenol

Copper-Catalyzed Synthesis of Hindered Ethers from α-Bromo Carbonyl Compounds was written by Zhou, Zhe;Behnke, Nicole Erin;Kurti, Laszlo. And the article was included in Organic Letters in 2018.Name: 4-Benzyloxyphenol The following contents are mentioned in the article:

In the presence of CuBr·SMe₂ and tricyclohexylphosphine, α-bromo-α,α-disubstituted carboxamides and carboxylic acids underwent chemoselective etherification and thioetherification reactions with alcs. and thiols at ambient temperature without exclusion of water and air to yield the corresponding ether- and thioether-substituted carboxamides and carboxylic acids. The method was used to prepare a quinolinylmethylphosphonate intermediate for protease-activated receptor 1 (PAR-1) antagonists which was unstable to previous etherification methods. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Name: 4-Benzyloxyphenol).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Name: 4-Benzyloxyphenol
