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 ...

Autoinductive Effects in Zinc‐Catalyzed Alkylations of Benzaldehyde Mediated by Simple Chiral β‐Amino Alcohol Ligands

ChemistryEurope, EarlyView.
The first report on zinc‐catalyzed enantioselective alkylation of aldehydes mediated by a chiral auxiliary is revisited, and the studies show much more complex behavior than previously thought. Studies show an enantiodivergence of the reaction as a function of its progress, due to an autoinduction phenomenon.
