Enantioselective Access to Trifluoromethylated Spirocyclopropyl Heterocycles
Advanced Science, EarlyView.We report a rhodium‐catalyzed asymmetric [2+1] spirocyclopropanation of methylene azacycles with trifluoromethyl carbenes in situ derived from fluoroalkyl triftosylhydrazones. ABSTRACT Chiral spirocyclopropyl heterocycles have emerged as privileged three‐dimensional structural motifs in medicinal chemistry.

Photosensitizing Au(I) Catalysis With Coumarins
Chemistry – A European Journal, EarlyView.A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate
Chemistry – A European Journal, EarlyView.A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

From Data to Dimers: Engineering Acene Derivatives for Photovoltaic Singlet Fission
Chemistry – A European Journal, EarlyView.Excited‐state energies of acene derivatives are predicted using a ChemBERTa‐based regression model and subsequently used to screen candidates for photovoltaic singlet fission using dimer–monomer benchmarked energetic criteria. Promising candidates are predominantly 5‐ and 6‐fused heteroacenes, which offer enhanced stability and higher triplet energies ...
