A look at the Williamson ether synthesis mechanism
Anisole is produced by the reaction of sodium phenoxide with methyl bromide and Williamson ether synthesis.
Williamson ether synthesis - Wikipedia
Anisole, also known as methoxybenzene can be described as an organic compound and colourless liquid with smell similar to that of anise seed. Anisole is prepared synthetically and is a precursor of other synthetic compounds and it is an ether. The chemical formula of anisole is CH3OC6H5. Anisole has a good solubility in diethyl ether, ethanol, benzene, chloroform, toluene and most of the organic solvents. It is used as a solvent, insect pheromone, and as an intermediate in manufacturing of dyes, fragrances, pharmaceuticals, etc. Anisole is generally supplied to end-users in drums or specially constructed tanks for hazardous liquids commonly called as ISO TANKS. Anisole suffers electrophilic aromatic reaction quicker than benzene, which reacts relatively quicker than nitrobenzene. Anisole is produced by the reaction of sodium phenoxide with methyl bromide and Williamson ether synthesis.
The catalytic Williamson ether synthesis (CWES) at high temperatures is especially well-suited for the production of alkyl aryl ethers such as anisole, neroline, and 4-methyl anisole which are of industrial importance.
What is Williamson's ether synthesis? - Quora
The of ethers uses the nature of alkoxide ions to react with primary alkyl halides using an SN2 . Thus, the reaction of sodium isoproproxide reacts with n-butyl iodide to produce the asymmetric ether n-butyl isopropyl ether. Primary alkyl halides are used to minimize the E2 reaction mechanism. In a method analoguos to the hydration of , ethers can be formed by reacting alkenes with an and an acid catalyst, or with an alcohol and mecury acetate. The Williamson synthesis, but not alkene-based methodes, can also be used to from cyclic ethers like tetrahydrofuran. To produce , a primary alkane is used that contains a halide atom at one end and an alcohol on the other end to undergo an . The addtion of the strong base (NaOH) creates an alkoxide ion from the alcohol. The alkoxide end reacts with the halogenated carbon in an SN2 mechanism, cyclizing the compound while eliminating the halogen atom. Thus, 4-chloro-1-butanol, in the presence of sodium hydroxide, produces tetrahydrofuran. , also called epoxides are class of cyclic ethers with only two carbon atoms and one oxygen atom in the ring structure. In addition to the Wiliamson ether synthesis (in which case the starting material, which has neighbouring hydroxyl and halide groups, is called a halohydrin), oxiranes may be formed by reacting an with a peroxyacid, a carboxylic acid with the OH group replaced by an OOH group. The most common of these is meta-chloroperbenzioc acid (mCPBA).
