Phenol ether - Wikipedia

WebWhen contrasting general anesthetic inductions by inhalational agents, New York’s Emery A. Rovenstine, M.D. (1895–1960), characterized ether as the “beer” and cyclopropane as the “champagne.” (Copyright © the American Society of Anesthesiologists, Inc.) 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).
