Medina-Mercado, Ignacio et al. published their research in ACS Catalysis in 2021 | CAS: 103-16-2

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Synthetic Route of C13H12O2

Gold-Catalyzed Ascorbic Acid-Induced Arylative Carbocyclization of Alkynes with Aryldiazonium Tetrafluoroborates was written by Medina-Mercado, Ignacio;Colin-Molina, Abraham;Barquera-Lozada, Jose Enrique;Rodriguez-Molina, Braulio;Porcel, Susana. And the article was included in ACS Catalysis in 2021.Synthetic Route of C13H12O2 The following contents are mentioned in the article:

Herein, arylative carbocyclization of alkynes 2-R-4-R1-C6H3XCH2CCR2 (X = O, S, NTs; R = H, I; R1 = H, OMe, Br, Ph, etc.; R2 = n-Bu, Ph, thiophen-2-yl, etc.) catalyzed by gold was described. In this process, Au(I) is oxidized to Au(III) with aryldiazonium tetrafluoroborates R3C6H4N2BF4 (R3 = 4-NO2, 3-CN, 4-C(O)OEt, etc.) following a photosensitizer-free and irradiation-free protocol. Ascorbic acid acts as a radical initiator, generating aryl radicals. According to DFT calculations, these radicals are added to Au(I), leading to a Au(II) species that is further oxidized to Au(III) with the assistance of a tetrafluoroborate anion. The overall arylative carbocyclization process is very energetically favorable, transforming arylpropargyl ethers into valuable 3,4-diaryl-2H-chromenes I in a completely regio- and stereoselective fashion. Furthermore, one of the synthesized 3,4-diaryl-2H-chromenes I exhibits polymorphism with marked differences in the color of its crystals, a property that could lead to the development of colored derivatives in the future. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Synthetic Route of C13H12O2).
