黄耀曾等发现,全氟丁炔-[2]酸甲酯在水溶液中低温皂化时,发生一种特殊的重排,烷氧基迁移到β碳原子上,形成烯醚酸,称为快酯-烯醚重排。本工作包括全氟丁快[2]酸仲丁酯的合成和考察其在低温皂化反应中一个空间位阻较大的仲丁氧基是否发生碳碳的1,3迁移。全氟快酸酯的合成路线如下: Huang Yao et al found that perfluorobutyne- [2] methyl ester in aqueous solution at low temperature saponification occurs when a special rearrangement, alkoxy transfer to the beta carbon atoms, the formation of enamel acid, called fast ester - Ether rearrangement. This work included the synthesis of sec-butyl perfluorodimethane [2] and the investigation of the 1,3-migration of carbon-carbon in a sterically hindered sec-butoxy group in a low-temperature saponification reaction. The synthesis of perfluorinated ester is as follows:
