Ring Opening Of Epoxides

Ring-opening of epoxides furnishing either linear or branched products belongs to the group of classic transformations in organic synthesis. However, the regioselective cross-electrophile coupling of aryl epoxides with aryl halides still represents a key challenge. Herein, we report vitamin B12/Ni dual-catalytic system that allows for the selective synthesis of linear products under blue-light irradiation.
