Regeneration of the organocatalytic column was also partially accomplished, although associated with a slightly lower enantioselectivity, thus prolonging the life of the reactor to more than 300h.doi:10.1002/ijch.201300106Riccardo PortaDipartimento di Chimica, Università degli Studi di Milano, Via Golgi ...

In such a well-designed process, the oxidation state of the metal in the catalyst would remain the same, thus, making it catalytic in [M] and free of any oxidants for the regeneration of catalyst in many of C–H functionalization reactions11–16. Herein, we wish to report the realization...
