Reaction of dimethyl-sulfoxonium methylide with non-halogenated α-ethylenic-ketones is known to lead to cyclopropyl derivatives. With α-fluoro α-ethylenic-ketones this reaction furnishes fluoro-epoxides, by addition of a methylene on carbonyl.
已知二甲基亚砜基亚甲基与未卤代的α-乙烯酮的反应可生成环丙基衍生物。对于α-氟代α-乙烯酮,该反应通过在羰基上加成亚甲基而提供氟代环氧化物。
