Mutual activation: Suzuki-Miyaura coupling through direct cleavage of the sp 2 C-O bond of naphtholate

Abstract

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 sp 2 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. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
