Cyclopropane was discovered in 1881 by August Freund, who also proposed the correct structure for the substance in his first paper. Freund treated 1,3-dibromopropane with sodium, causing an intramolecular Wurtz reaction leading directly to cyclopropane. The yield of the reaction was improved by Gustavson in 1887 with the use of zinc instead of sodium. Cyclopropane had no commercial application until Henderson and Lucas discovered its anaesthetic properties in 1929…

WebMethoxypropane, or methyl propyl ether, is an ether once used as a general anaesthetic. It is a clear colorless flammable liquid with a boiling point of 38.8 °C. Marketed under the trade names Metopryl and Neothyl, methoxypropane was used as an alternative to diethyl ether because of its greater potency. http://qinchengxin.com/zh/product-1ST20600-1000Ht

WebCyclopropane is necessarily planar (flat), with the carbon atoms at the corners of an equilateral triangle.

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).
