WebThe general structure of a phenol ether. In chemistry, a phenol ether (or aromatic ether) is an organic compound derived from phenol (C 6 H 5 OH), where the hydroxyl (-OH) group is substituted with an alkoxy (-OR) group. Usually phenol ethers are synthesized through the condensation of phenol and an organic alcohol; however, other known ... 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.
