Abstract

Abstract Palladium-catalyzed decarboxylative coupling of benzoic acid derivatives with arylboroxins gave biaryls using a catalytic amount of Pd (TFA) 2–hydrazone 1d system with Ag 2 CO 3 at 80 C in good yields. We also found that decarboxylative coupling with aryl (trialkoxy) silanes gave biaryls using a Pd (TFA) 2–hydrazone 1g system with AgF in good yields.
