Mutual Activation: Suzuki–Miyaura Coupling through Direct Cleavage of the sp2 CO Bond of Naphtholate

Working together: A new approach of mutual activation between naphtholates and aryl boronic acid derivatives by the formation of borates to facilitate the Suzuki–Miyaura coupling through direct cleavage of the sp2 CO bond by nickel catalysis is described (see scheme; R′: annulated ring system). Various naphtholates and aryl boronic acid derivatives could be directly coupled in good yields.
