WebSep 15, 2010 · Abstract. This reaction is a nucleophilic substitution of an alkali alkoxide on an alkylating reagent to form an ether and an inorganic salt and is generally referred to … WebThus, Williamson was able to dispel the notion that diethyl ether and dimethyl ether can each arise from their respective carbon sources, potassium ethylate and methyl iodide, but rather there is a union of the carbon residues of each reactant to form "this remarkable body", ethyl methyl ether. In yet another experiment, he demonstrated that ...

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. WebWilliamson Ether Synthesis When a primary or secondary alkyl halide reacts with an alkoxide, the product of the reaction is an ether. One side of the ether is an alkyl chain from the alkyl halide, and the other side is an alkyl chain that came from the alkoxide. An alkoxide is any RO – group.
