Enabling Cross‐Coupling Reactivity of α‐Pentafluorosulfanyl Compounds with a Thermally Stable Organozinc α‐SF5 Reagent

Chemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.
This work describes the first example of a thermally stable α‐SF5 organometallic reagent, which allows for extensive downstream functionalization by allylation and acylation reactions under copper catalysis, as well as palladium‐catalyzed Negishi‐type cross‐coupling conditions up to 96% yield. In silico analysis shines initial light on the requirements

Redox‐Tuned Oxycarbamates Enable Divergent C─N and C─C Functionalization of Indolizines Under Photoredox Catalysis With Green Light

Chemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.
Nonafluoromesitylsulfonyl (Nms)‐substituted oxycarbamates are introduced as redox‐lowered radical precursors for green‐light photoredox synthesis. Selective N─O bond cleavage generates amidyl radicals that directly aminate indolizines in DMF, whereas DMSO promotes 1,2‐hydrogen atom transfer (HAT) to α‐amino carbon‐centered radicals and C─C bond ...

Photochemical and Thermal Activation of a Diarylbismuth Azide

Chemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.
We report the synthesis and characterization of a novel diarylbismuth azide and its divergent reactivity upon thermal or photochemical activation. These findings contribute expanding the reactivity landscape of heavy pnictogen compounds and sets the basis for further investigations. ABSTRACT Azides are widely employed in synthesis as convenient nitrene

Tandem Synthesis and Photophysical Behavior of Pyrazolo[3,4‐h][1,6]naphthyridines: A Theoretical–Experimental Approach

European Journal of Organic Chemistry, Volume 29, Issue 41, 3 November 2026.
A tandem reaction of 5‐aroylpyrazolo[3,4‐b]pyridines with malononitrile and methanol to access pyrazolo[3,4‐h][1,6]naphthyridines was achieved in 60%–66% yield under microwave conditions. The tricyclic fluorophoric core bears groups of different stereoelectronic nature (i.e., alkyl, aryl, MeO, and CN), and thus their optoelectronic activity shows ...
