Síntesis de éteres de Williamson

C2H5ONa + CH3I → C2H5OCH3 + NaI

Descripción general

Sodium ethoxide (an alkoxide) reacts with methyl iodide in an SN2 reaction to form ethyl methyl ether. This is the most general and reliable method for synthesizing asymmetric ethers. The alkoxide acts as the nucleophile, and a primary alkyl halide provides the best yields.

Ejemplo cotidiano

MTBE (methyl tert-butyl ether), once the most widely used gasoline additive, was produced by a variation of ether synthesis.

Importancia industrial

Método clásico en síntesis orgánica para la preparación de éteres simétricos y asimétricos en farmacéutica.
