Metal Porphyrin Catalyzed Olefin Aziridination with Sulfonyl Azides

Cobalt(II) complex of P1 [Co(P1)], a new porphyrin that was designed on the basis of potential hydrogen bonding interactions in the metal-nitrene intermediate, is a highly active catalyst for olefin aziridination with azides. The [Co(P1)]-based system can be effectively employed for different combinations of aromatic olefins and arysulfonyl azides, synthesizing various sulfonylated aziridines in excellent yields. Besides its mild catalytic conditions, the Co-catalyzed aziridination process enjoys several attributes associated with the relatively low cost of cobalt and widely accessible arylsulfonyl azides. Furthermore, it generates stable dinitrogen as the only by-product.
