WebJan 27, 2024 · Preparations of Ethers by Williamson Synthesis. Both symmetrical and unsymmetrical ethers can be prepared using Williamson synthesis, named after Alexander William Williamson, in the year \(1850\). It is an \({{\rm{S}}_{\rm{N}}}2\) reaction. An alkyl halide is made to react with sodium alkoxides to yield Ether. WebDimethyl ether (DME; also known as methoxymethane) is the organic compound with the formula CH 3 OCH 3, (sometimes ambiguously simplified to C 2 H 6 O as it is an isomer of ethanol).The simplest ether, it is a colorless gas that is a useful precursor to other organic compounds and an aerosol propellant that is currently being demonstrated for use in a …
