Phenolic methyl ethers
WebFor example, ethyl methyl ether (CH 3 OC 2 H 5), diphenylether (C 6 H 5 OC 6 H 5). As for other organic compounds, very common ethers acquired names before rules for nomenclature were formalized. ... Since phenols are acidic, they readily react with a strong base like sodium hydroxide to form phenoxide ions. Phenol ethers can be synthesized through an acid-catalyzed condensation of phenols and an alcohol. Phenols include phenol itself, benzenediols, polyphenols, and other phenol-derived molecules. However, this synthesis risks the self-condensation of alcohol itself (e.g. ethanol self-condenses to form diethyl ether). … See more In chemistry, a phenol ether (or aromatic ether) is an organic compound derived from phenol (C6H5OH), where the hydroxyl (-OH) group is substituted with an alkoxy (-OR) group. Usually phenol ethers are synthesized through … See more Phenol ethers, similarly to regular ethers, are less hydrophilic than its precursors, phenols and alcohols, both of which can donate and accept … See more Phenol ethers follow the same nomenclature of regular ethers; ethers have the structure R-O-R’, but phenol ethers require that one of the substituents to be a phenyl group (abbreviated Ph), signifying a simple general structure of Ph-O-R’. As a result, the See more Phenol ethers are often utilized in pharmaceutical design as a substituent that acts as a hydrogen-bond acceptor but not a hydrogen-bond donor; this allows many oral medications to follow Lipinski’s rule of five.

Anisole, or methoxybenzene, is an organic compound with the formula CH3OC6H5. It is a colorless liquid with a smell reminiscent of anise seed, and in fact many of its derivatives are found in natural and artificial fragrances. The compound is mainly made synthetically and is a precursor to other synthetic compounds. Structurally, it is an ether (−O−) with a methyl (−CH3) and phenyl (−C6H5) group attached. Anisole is a standard reagent of both practical and pedagogical value. WebNational Center for Biotechnology Information. 8600 Rockville Pike, Bethesda, MD, 20894 USA. Contact. Policies. FOIA.
