Orthogonal One‐Pot Dual Catalysis Enabled by a Hybrid Chiral Diene/Phosphine Ligand

Advanced Synthesis &Catalysis, Volume 368, Issue 14, 17 July 2026.
A hybrid chiral diene–phosphine ligand enables orthogonal one‐pot Rh/Pd relay catalysis, delivering high yields and enantioselectivities while outperforming dual‐ligand systems. A hybrid chiral diene‐phosphine ligand (L1) enables orthogonal one‐pot relay catalysis by integrating distinct metal‐coordination sites within a single molecular framework. The

Pt/C‐Catalyzed Deuteration of Polycyclic Aromatic Hydrocarbons with Suppressed Arene Hydrogenation

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
An additive‐enabled Pt/C protocol promotes hydrogen–deuterium exchange in fused polycyclic aromatic hydrocarbons (PAHs) in D2O/2‐PrOH at 80 °C. Decalin suppresses undesired ring hydrogenation while accelerating on‐ring H–D exchange, furnishing highly deuterated PAHs (PAHs‐dn).
