Avoiding additives: A highly efficient and mild Pd‐catalyzed decarboxylative ortho‐acylation of azobenzenes with α‐oxocarboxylic acids was developed that provides an alternative route to acylated azo compounds. This decarboxylative acylation process was completed in the absence of any additives at ambient temperature, to afford the acylated azobenzenes in moderate to good yields (see scheme).
避免添加剂:A高效和温和的Pd-催化的脱羧邻用α-氧代羧酸偶氮苯的酰化的开发,提供了酰化的偶氮化合物的替代路线。在环境温度下在不存在任何添加剂的情况下完成该脱羧酰化过程,以中等至良好的产率得到酰化的偶氮苯(参见方案)。
