【摘要】 <正> 前文报道全氟丁炔-[2]酸和全氟已炔-[2]酸甲酯及乙酯在水溶液中低温皂化时,发生一种特殊的重排,我们称之为炔酯-烯醚重排.烷氧基迁移到β碳原子上,形成烯醚酸.并报道了产物的构型和重排机理。本文报道全氟丁炔-[2]酸仲丁酯(1)的合成及其皂化反应。通过分子内Wittig反应,合成了有特殊刺激臭味的无色透明液体1。更多还原

【Abstract】 The intramolecular Wittig reaction has been applied to the synthesis of sec-butyl perfluorobutynoate. The saponification of the product with aqueous sodium hydroxide gave 3-sec-butoxy-4, 4, 4-trifluoro- [2] butenoic acid and 4,4,4-trifluoro-3-oxo butyric acid in 1:5 ratio.更多还原
