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. 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.
