Synthesis of Aromatic Aldehydes by CH Formylation of Aromatics with Silyl Formates Prepared from CO2 and Hydrosilanes

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
A new method has been developed for the C–H formylation of aromatic compounds using silyl formates synthesized from CO2 and hydrosilanes. This is the first report on the direct C–H formylation of aromatics with silyl formates. The formylation reactions were promoted by BBr3 or BCl3. The reaction mechanism has been clarified by DFT calculations. Despite

Synthesis of β‐Enamino Sulfoxides via Cine‐Substitution of 1‐Chlorovinyl p‐Tolyl Sulfoxides with Lithium Amides

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
The cine‐substitution of 2‐aryl‐1‐chlorovinyl p‐tolyl sulfoxides with lithium amides yields β‐enamino sulfoxides with high efficiency. β‐Enamino sulfoxides are desulfinylated via the sulfoxide/magnesium exchange reaction with isopropylmagnesium chloride to yield enamines.

Mild N‑Arylation of Sulfoximines With (Hetero)aryl Chlorides Enabled by α‐Methylnaphthyl‐tBuBrettPhos Palladium Triflate

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
A readily accessible, air‐ and moisture‐stable palladium precatalyst, [Pd(1‐MeNAP)(tBuBrettPhos)]OTf, enables the direct N‐arylation of NH‐sulfoximines with (hetero)aryl chlorides under exceptionally mild conditions ideal for late‐stage diversification of drug‐like scaffolds.

Luminescent Donor‐Acceptor Radical With Propeller Chirality: Bright and Photostable Red Circularly Polarized Luminescence and Whispering Gallery Mode Resonance

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
A series of donor‐attached brominated chiral luminescent radicals (CzTTBrM, 2CzTTBrM, and 3CzTTBrM) was synthesized, showing red to near‐infrared (NIR) circularly polarized luminescence (CPL) with exceptionally high PLQY of up to 76% and markedly enhanced CPL brightness (BCPL). Doping into polystyrene microspheres further yields whispering gallery mode

1,1‐Disubstituted Vinylbromides: Versatile Building Blocks for the Synthesis of Nitrogen‐Containing Heterocycles

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
1,1‐Disubstituted vinylbromides are key intermediates for constructing nitrogen‐containing heterocycles. This review provides an overview of the synthetic applications of 1,1‐disubstituted vinylbromides and summarizes recent developments in reaction methodologies, mechanistic insights, and the structural diversity of N‐heterocyclic compounds accessible
