The study of the Julia–Kocienski reaction between fluorinated arylsulfone and ketones is described. The corresponding fluoroalkenes were isolated in moderate to good yields from β- and δ-substituted cyclic ketones. From acyclic ketones and α-substituted cyclic ketones a decarbethoxylation reaction of the sulfonylesters occurred. This decarbethoxylation reaction opened a new route for the preparation
描述了氟化芳基砜与酮之间的Julia-Kocienski反应的研究。从β-和δ-取代的环酮以中等至良好的产率分离出相应的氟代烯烃。由无环酮和α-取代的环酮发生磺酰基酯的脱碳乙氧基化反应。该脱碳乙氧基化反应为制备各种氟代烷基砜作为制备氟代烯烃的潜在基石开辟了一条新途径。
