Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.

From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation

European Journal of Organic Chemistry, EarlyView.
Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐

A Photoredox Radical‐Polar Crossover Reaction for the Preparation of Monoprotected Dicarbonyl Compounds

European Journal of Organic Chemistry, EarlyView.
An ATRA‐based, Ru‐photocatalyzed radical‐polar crossover reaction for the preparation of monoprotected dicarbonyl compounds is reported. This procedure is based on the capture of a cationic intermediate, arising from the radical step, with diverse nucleophiles.
