| 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 Ag2CO3 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. |
