Pd(0)-Catalyzed Decarboxylative Coupling and Tandem C–H Arylation/Decarboxylation for the Synthesis of Heteroaromatic Biaryls
摘要:
An effective Pd(0) carbene complex was successfully employed in the decarboxylative coupling of the heteroaromatic carboxylic acids (imidazo[1,2-a]pyridine and isoxazole) with aryl halides. For carboxyindoles, either decarboxylative coupling or tandem C-H arylation and decarboxylation occurred, leading to the formation of C2-monoarylated indoles.
