A highly selective sp3 C–N cleavage of tertiary anilines was achieved using the TBN/TEMPO catalyst system. When N,N-diaklylanilines (alkyl, benzyl) were employed, the N–CH3 bond was selectively cleaved via radical C–H activation. Moreover, when the allyl group was installed, totally reverse selectivity was observed. It is worth noting that the solvent effect is also crucial to obtain high reaction
使用TBN / TEMPO催化剂系统可实现对叔苯胺的高选择性sp 3 C–N裂解。当使用N,N-二烯丙基苯胺(烷基,苄基)时,N–CH 3键通过C–H自由基活化被选择性裂解。此外,当安装烯丙基时,观察到完全相反的选择性。值得注意的是,溶剂效应对于获得高反应效率和选择性也至关重要。
