Rhodium-Catalyzed Decarbonylative Suzuki-Miyaura Cross-Coupling via in-Situ Generation of Acyl Fluorides from Carboxylic Acids

Abstract

The biaryl frameworks are momentous organic backbones that are commonly occurred in pharmaceutical, functional materials and natural products. By virtue of the distinctive reactivity through state-of-the-art process, decarbonylative couplings, which have bypassed the restriction to specifically substituted (hetero)aryl carboxylic acids of decarboxylative couplings, gradually become unneglected methods in the conversion of carboxylic acid derivatives. Herein, a rhodium-catalyzed decarbonylative Suzuki-Miyaura cross-coupling via in-situ generation strategy of acyl fluorides from carboxylic acids was developed. This protocol shows eminent functional group tolerance with arrays of combinations between carboxylic acid and boronic acid. Furthermore, the reaction offers a new access to those conventionally unattainable biaryl motifs, including natural product and modified drugs.
