Addition of Olah's reagent in benzene or methylene chloride to azirines leads to the formation of difluoroamines or α-fluoroketones. This reaction has been applied to the synthesis of 17 α-fluoropregnenolone. The formation of fluoroketone proceeds via a cationic intermediate. Yield is improved when using a more nucleophilic fluorinating reagent obtained by addition of triethylamine to Olah's reagent
将Olah试剂在苯或
二氯甲烷中的
叠氮基添加到
叠氮基中会导致形成
二氟胺或α-
氟酮。该反应已应用于17α-
氟孕烯醇酮的合成。
氟代酮的形成通过阳离子中间体进行。当使用通过向奥拉试剂中添加
三乙胺而获得的更具亲核性的
氟化试剂时,收率得到提高。
