윌리엄슨 에터 합성
C2H5ONa + CH3I → C2H5OCH3 + NaI
개요
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.
일상 속 예시
MTBE (methyl tert-butyl ether), once the most widely used gasoline additive, was produced by a variation of ether synthesis.
