Palladium-catalyzed decarboxylative coupling of benzoic acid derivatives using hydrazone ligands
摘要:
Palladium-catalyzed decarboxylative coupling of benzoic acid derivatives with arylboroxins gave biaryls using a catalytic amount of Pd(TFA)(2)-hydrazone Id system with Ag2CO3 at 80 degrees 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. 2014 Elsevier Ltd. All rights reserved.
