WebThe Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol (alkoxide). This reaction was developed by Alexander Williamson in 1850. Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an SN2 reaction. WebThis synthesis consists of an Sy2 reaction of a sodium alkoxide with an alkyl halide, alkyl sulfonate, or alkyl sulfate. This route allows the formation of asymmetric ethers, which are cthers with two different R groups. …
