Low‐Valent Cobalt‐Catalyzed Deprotection of Allyloxyarenes

Herein, we report a low-valent cobalt-catalyzed deprotection of allyloxyarenes. The method displays a broad substrate scope and good functional group tolerance, granting its utilization on more complex substrates, including O-allylated derivatives of natural products and drugs. Based on comprehensive experiments, a plausible mechanistic pathway for the low-valent cobalt-catalyzed O-deallylation of allyloxyarenes is proposed.
