The name for this type of organic compound was first used in 1730 by F.G. Frobenius, and non-IUPAC names for some include anisole and phenetole. Used as solvents for Grignard reagents, and as inert media for reactions like the Grignard and Wurtz-Fittig reactions, along with esters, these can be tested for by splitting them with hydroiodic acid, known as the Zeisel method. These are soluble in organic liquids, but most are not soluble in water, an exception to which is dioxane, a (*) cyclic one of these. They are generally synthesized by reacting alkyl halides with sodium alcoholates, a process known as Williamson synthesis. Featuring two R groups connected to an oxygen, FTP, name this group of organic compounds whose diethyl type is often used as an anasthetic.
