Synthesis of Mixed Phosphine–Phosphine Oxide Ligands by Rh(I)‐Catalyzed C─H Bond Alkylation
ChemCatChem, EarlyView.An efficient method for the synthesis of mixed phosphine–phosphine oxide ligands via Rh(I)‐catalyzed C─H bond alkylation of biarylphosphines was developed. The resulting hemilabile ligands demonstrate high reactivity in Pd‐catalyzed Buchwald–Hartwig coupling with ammonia, achieving excellent yields. This work highlights the potential of mixed phosphine–

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 ...

Copper Photoredox‐Catalyzed Allylation of Imines with Allylic Bromides
ChemCatChem, EarlyView.[Cu(neocuproine)(DPEphos)]PF6 ([Cu(NN)(PP)]+) has been developed as a copper photocatalyst for the allylation of imines with allylic bromides. The transformation can be applied to a variety of imines, and the mechanism is believed to involve the direct addition of an allylic radical to the C═N bond.

Group I tert‐Amylates: A Comparative Study in Hydrophosphination Reactions
ChemCatChem, EarlyView.A comparative study of group I tert‐amylate precatalysts for hydrophosphination demonstrates increasing reactivity down the group to the first examples of rubidium and cesium in this reaction. Catalytic activity with lighter and more abundant elements, typified by potassium, can be enhanced with a crown ether, demonstrating the importance of ion ...
