Thus, methyl iodide, on heating with alcoholic sodium methoxide forms dimethyl ether.
WebThe intramolecular Williamson reaction has been widely applied to the synthesis of oxetanes and is one of the two most commonly used methods. Starting materials are alcohols having a good leaving group at the γ-position, such as bromine, chlorine or tosylate, and cyclization is achieved by treatment with base, usually with heat.
