Cobalt-catalyzed radical cyclization of isocyanides forming phenanthridine derivatives

A neutral cobalt( ii ) compound Cp*Co(1,2-Ph 2 PC 6 H 4 S) ( 1 , Cp* = Me 5 C 5 − ) catalyzes the radical cyclization of 2-isocyano-biphenyls with alkyl halides, providing a variety of 6-substituted phenanthridines and phenanthridine-fused polycyclic compounds in good to excellent yields. The mild r...
