Adding 2Ns: Palladium catalysis introduces two nitrogen groups in a new regio and chemoselective diamination of non‐activated alkenes that proceeds under entirely intermolecular reaction control. This palladium‐catalyzed reaction employs commercial nitrogen sources in combination with a hypervalent iodo(III) reagent as oxidant (see scheme; Tos=toluenesulfonyl).
添加2Ns:钯催化在新的非活化烯烃的区域和化学选择性加成中引入两个氮基,该加成反应在完全分子间反应的控制下进行。该钯催化的反应使用商业氮源与高价碘(III)试剂作为氧化剂(请参阅方案; Tos =甲苯磺酰基)。
