Abstract
A new strategy for the synthesis of 2-arylbenzoxazole derivatives via nickel-/copper-catalyzed decarbonylative heteroarylation of aryl anhydrides via C-O/C-H coupling has been developed. The reaction is promoted by a user-friendly, inexpensive, and air- and moisture-stable Ni precatalyst. A variety of 2-arylbenzoxazole derivatives have been successfully synthesized and have good functional group tolerance in this process, which afforded products in moderate-to-excellent yields.
