Decarboxylative cross‐coupling reactions of substituted 2‐carboxyazine N‐oxides, with a variety of (hetero)aryl halides, by bimetallic Pd0/CuI and Pd0/AgI catalysis are reported. Two possible pathways, a conventional bimetallic‐catalyzed decarboxylative arylation, as well as a protodecarboxylative/direct CH arylation sequence have been considered. These methods provide the first general decarboxylative
据报道,通过双金属Pd 0 / Cu I和Pd 0 / Ag I催化,取代的2-羧嗪N-氧化物与各种(杂)芳基卤化物发生脱羧交叉偶联反应。两种可能的途径,传统的双金属催化的芳基化脱羧,以及一个protodecarboxylative /直接ç ħ芳基化序列已被考虑。这些方法为2-羧嗪系列提供了第一个通用的脱羧芳基化方法。
