An oxy-palladation, formal Wagner–Meerwein rearrangement and fluorination cascade has been established for generating fluorinated oxazolidine-2,4-diones and oxazolidin-2-ones. The reaction has a broad substrate scope in which both aryl and alkyl groups can be utilized as efficient migrating groups. Experimental evidence suggests that the reaction is initiated by anti-oxy-palladation of the olefin,
建立了氧合pal合,正式的Wagner-Meerwein重排和氟化级联反应,用于生成氟化的oxazolidine-2,4-diones和oxazolidin-2-ones。该反应具有广泛的底物范围,其中芳基和烷基均可用作有效的迁移基团。实验证据表明,该反应通过引发抗烯烃氧基- palladation,随后通过氧化产生的烷基的Pd IV中间体和协调一致的迁移氟化。
