A radical solution: A Bu4NI/tert‐butyl hydroperoxide (TBHP) catalyzed synthesis of amides through a cross‐coupling reaction between acyl and aminyl radicals is described. This method involves the combination of aldehyde CH bond functionalization and decarbonylation of N,N‐disubstituted formamides (see scheme). The cross‐coupling is metal‐free, has a wide substrate scope, operational simplicity, and
自由基溶液:描述了Bu 4 NI /叔丁基过氧化氢(TBHP)通过酰基和氨基自由基之间的交叉偶联反应催化的酰胺合成。该方法涉及醛CH键官能化和N,N-二取代甲酰胺的脱羰作用的组合(请参见方案)。交叉耦合是无金属的,具有广泛的基片范围,操作简便,并且按比例放大可提供高产量。
