A highly effective cobalt catalyst for olefin aziridination with azides: Hydrogen bonding guided catalyst design

Article abstract of DOI:10.1021/ol800588p

[Co(P1)], which was designed on the basis of potential hydrogen-bonding interactions in the metal-nitrene Intermediate, Is a highly active aziridination catalyst with azides. [Co(P1)] can effectively azlridlnate various aromatic olefins with arylsulfonyl azides under mild conditions, forming sulfonylated aziridines in excellent yields. The Co-based system enjoys several attributes associated with the relatively low cost of cobalt and the wide accessibility of arylsulfonyl azides. Furthermore, it generates stable dinitrogen as the only byproduct.
