Article Synopsis
- - The study introduces a new method for oxyaminating alkenes using sulfonamides, facilitated by WODipic(HO), resulting in high yields and selectivity for various types of alkenes.
- - A detailed catalytic cycle is proposed, which includes the formation of a tungstenooxaziridine complex as the active catalyst, with hydrolysis of a tungstenooxazolidine intermediate being the slowest step.
- - Initial experiments on kinetics and competition support the validity of the proposed mechanism behind this oxyamination reaction.
Herein, we report the catalytic allylic amination of α-methylalkenes with VODipic(HMPA) and chloramine T as the quantitative source of . The reaction works with high yields and stereoselectivities for α-methylalkenes. A proposed tosylnitrene-free catalytic cycle involving the formation of vanadoxaziridine complex as the active catalyst and aminovanadation across the substrate as the rate-determining step has been proposed.
