Concentrated sulfuric acid promoted the intramolecular dehydration and 1,3-sulfanyl migration of 1,1,1-trifluoro-4,4-bis(arylthio)butane-2,2-diol; this afforded, in addition to the expected unsaturated ketone, an unexpected trifluoromethyl-containing bridged heterocycle.
浓硫酸促进了1,1,1-三氟-4,4-双(芳基硫)丁烷-2,2-二醇的分子内脱水和1,3-硫迁移;这种反应除了得到预期的非饱和酮外,还意外获得了一种含有三氟甲基的桥接杂环。
