dehydrogenative amidation of azoarene using air as the terminal oxidant was developed. Various amides, such as arylamides, alkylamides, lactams, and imides, are all effective amidation reagents and provide the desired products in moderate to excellent yields. Notably, good yields can also be obtained on a gram-scale with this amidation reaction. In this protocol of azoarene amidation, the catalyst (Cu(OAc)2)
提出了一种以空气为末端氧化剂的Cu(II)催化的偶氮芳烃脱氢酰胺化方法。各种酰胺,例如芳基酰胺,烷基酰胺,内酰胺和酰亚胺,都是有效的酰胺化试剂,并以中等至优异的产率提供所需的产物。值得注意的是,通过该酰胺化反应,也可以以克为单位获得良好的产率。在该偶氮芳族酰胺化方案中,催化剂(Cu(OAc)2)和氧化剂(空气)便宜且容易获得,并且该方法高效且原子经济。
