Palladium catalysis enables the regioselective difunctionalization of alkenes using saccharin as the nitrogen source in the initial step of aminopalladation. Depending on the reaction conditions, diamination or aminooxygenation pathways can be accessed using hypervalent iodine reagents as the terminal oxidants. The aminooxygenation of allylic ethers originates from an unprecedented ambident behavior

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)。
