Cobalt-Catalyzed Efficient Aziridination of Alkenes
摘要:
Cobalt porphyrins are capable of catalyzing the azirldination of alkenes with bromamine-T as the nitrene source. Among cobalt complexes of different porphyrins, Co(TDCIPP) is an effective catalyst that can aziridinate a wide variety of alkenes. The catalytic system can operate at room temperature in a one-pot fashion with alkenes as limiting reagents, forming the desired N-sulfonylated aziridine derivatives in high to excellent yields with NaBr as the byproduct.
