Ether williamson
WebOne very important route to synthesizing ethers was discovered by British chemist, Alexander Williamson. In this reaction, an alkoxide ion (RO) reacts with an alkyl halide or tosylate via an Sx2 mechanism. This route allows the formation of asymmetric ethers, which are ethers with two different groups.
