Photoredox/Pyridine N‐Oxide Catalyzed Acyl Radical Generation From Aldehydes for Divergent Synthesis of Pyrroles and Carbocyclic Ketones

Advanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.
Pyridine N‐oxides serve as photoinduced HAT catalysts to convert simple aldehydes into acyl radicals catalyzed by organophotocatalysts. Reacting these intermediates with alkynes opens aldehyde‐dependent pathways to densely functionalized pyrroles, substituted cyclopentanones, and indanones.

Unlocking the Potential of Organoaluminum Reagents for Versatile C─C Couplings Using YPhos‐Pd Catalysts

Advanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.
A general C─C cross‐coupling method employing earth‐abundant organoaluminium nucleophiles is enabled by electronically highly donating and sterically demanding ylide‐substituted phosphine (YPhos) ligands under Pd catalysis. This protocol represents an organoaluminium cross‐coupling that operates with a single catalyst system across all carbon ...

Nickel‐Catalyzed Reductive Cross‐Coupling of Xanthate Esters With Aryl and Alkenyl Iodides

Chemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.
A nickel‐catalyzed reductive cross‐coupling of xanthate esters and aryl/alkenyl iodides is reported without the need for separate activators for the xanthate esters. The reaction utilizes a relatively low catalyst loading. Diarylmethanes with a good functional group variety can thus be synthesized indirectly from the corresponding benzylic alcohols ...

Synergistic Action of Ascorbic Acid and Readily Accessible NHC^N Ligands for the Oxidation of Gold(I) With Electron‐Rich Aryldiazonium Salts

Chemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.
The synergic action of ascorbic acid and NHC^N ligands enables Au(I) oxidation with electron‐rich aryldiazonium salts. ABSTRACT The synergistic action of ascorbic acid and NHC^N ligands enables the challenging oxidation of Au(I) with electron‐rich aryldiazonium salts in the absence of a cocatalyst and/or irradiation. EPR, NMR, and x‐ray analyses reveal

Catalytic C–F Bond Activation at Room Temperature: Enolate Cross‐Couplings Enabled by [Pd(1‐MeNAP)TFA]2 and LiHMDS

Angewandte Chemie International Edition, Volume 65, Issue 38, 14 September 2026.
Catalysts generated from the trifluoroacetate‐bridged methylnaphthyl‐palladium dimer [Pd(1‐MeNAP)TFA]2 and biarylphosphine ligands in combination with the base LiHMDS promote α‐arylation reactions of various enolates with non‐activated aryl fluorides at room temperature.
