摘要
The influence of aryl substituents in dibenzylidene acetone (dba) ligands, for Pd(0) complexes, has been evaluated for Suzuki-Miyaura cross-coupling reactions. Electron-withdrawing substituents such as NO2 or CF3 deactivate the catalyst species whereas strongly donating substituents such as Me increase catalytic activity over that of unsubstituted dba ligands.
