Marsalek, Kamil et al. published their research in Organic Letters in 2020 | CAS: 102-09-0

Diphenyl carbonate (cas: 102-09-0) belongs to esters. 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. 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.COA of Formula: C13H10O3

Monofunctionalized Bambus[6]urils and Their Conjugates with Crown Ethers for Liquid-Liquid Extraction of Inorganic Salts was written by Marsalek, Kamil;Sindelar, Vladimir. And the article was included in Organic Letters in 2020.COA of Formula: C13H10O3 The following contents are mentioned in the article:

In this Letter, the first synthesis of monofunctionalized bambusurils I [R = (CH2)4COOH, 4-HO2CC6H4] and their use for preparation of heteroditopic bambusuril-crown ether conjugates suitable for extraction of ion pairs from water to chloroform was presented. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0COA of Formula: C13H10O3).
