The radical mechanism of cobalt(ii) porphyrin-catalyzed olefin aziridination and the importance of cooperative H-bonding†
Abstract
The mechanism of cobalt(II) porphyrin-mediated aziridination of C double bond of
O and N–H units. The computed radical-type mechanism agrees well with all available mechanistic and kinetic information. The computed free energy profile readily explains the superior performance of the CoII(porAmide) system with H-bond donor functionalities over the non-functionalized Co(TPP).
