β-fluorination reaction of cyclic amides, which is achieved by an oxidative-promoted selective hydrogen atom-transfer/isomerization/electrophilic fluorination process. Moreover, the combination of an N-hydroxy catalyst and Selectfluor allows α, β-dehydrogenation and γ-di-fluorination of N-aryl lactams to be established. Furthermore, the present selective catalysis also works well for the C–N bond cleavage of acyclic
本文描述了环酰胺的去饱和和β-氟化反应的发展,这是通过氧化促进的选择性氢原子转移/异构化/亲电氟化过程实现的。此外,N-羟基催化剂和 Selectfluor 的组合允许建立N-芳基内酰胺的 α、β-脱氢和 γ-二氟化。此外,目前的选择性催化也适用于非环状酰胺在不拥挤位点的 C-N 键断裂。该反应的机理已通过实验和计算研究进行了详细说明。
