α－氧代烯酮二硫代缩酮化学（XXXⅡ）──由2－（1，3－亚丙二硫基）亚甲基环己酮合成酚醚类化合物

The Chemistry of α-Oxo Ketene Dithioacetals(X X X Ⅱ)-Synthesis of Aryl Ethers via 2-(1,3-Dithiopropylene)methylene Cyclohexanone

２－（１，３－亚丙二硫基）亚甲基环己酮（１）与２－甲基烯丙基氯化镁加成得α－羟基烯酮二硫缩酮类化合物（２）．在各种开链脂肪醇存在下，（２）经酸催化的取代－环合芳构化反应生成酚醚类化合物（３）．

Dithopropylene)methylene cyclohexanone(1)rcacted with methallyl Grignard reagent produced the carbinol(2).Catalyzed by acid and in the presence of alcohols,(2)were converted to the aryl ethers(3)via the Substitution-Cycloaromatization Reaction.
