Bifunctional Aziridines from Photochemically Generated FSO2NH2 for SuFEx Diversification of Alkenes

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Photochemically generated FSO2NH2 serves as a safe, practical nitrene precursor for Rh‐catalyzed aziridination of alkenes, granting access to previously inaccessible fluorosulfonyl aziridines. These bifunctional electrophiles merge aziridine ring strain with SuFEx reactivity to provide a modular platform toward aliphatic sulfamoyl fluoride derivatives ...

Hoveyda–Grubbs 1st and 2nd Generation Precatalysts Modified in the Alkoxybenzylidene Part With Long (Fluorous) Chains: Catalytic Activity and Stability

European Journal of Organic Chemistry, Volume 29, Issue 2, January 16, 2026.
We synthesized a series of light to heavy fluorous Hoveyda–Grubbs precatalyst analogs modified in the alkoxybenzylidene part in positions 2 and 5 by long (fluorinated) ponytails and tested their activity in ring‐closing metathesis. The substitution mostly resulted in accelerated reaction but the precatalyst stability often decreased.
