Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates
ChemCatChem, EarlyView.The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...
