Deazaalloxazines – Flavin Derivatives That Provide Reductive Photoredox Catalysis with Inert Substrates

Chemistry – A European Journal, EarlyView.
7,8‐Dimethoxy‐5‐aryl‐5‐deazaalloxazines (dAll) are new class of photostable, visible‐light‐absorbing flavin derivatives which are strongly reducible upon excitation with 400 nm light. It was demonstrated on difficult‐to‐reduce aryl halides like bromo‐, chloro‐ and fluoroanisoles which were transformed to phosphonates by reductive cross‐coupling with ...

Metal‐Induced Tuning of Fullerene Reactivity: Application to Nucleophile Addition

ChemPhysChem, EarlyView.
A textbook case of how encapsulating an atom in a carbon cage can tune assembly reactivity based on partial charge distribution–exemplified by the classic nucleophilic attack. Endohedral metallofullerenes (EMFs) are a unique class of hybrid molecules formed by encapsulating metal atoms within carbon cages (fullerenes), giving rise to distinctive ...

Mid‐infrared Spectroscopy of Protonated Benzonitrile, 2‐Cyanonaphthalene, and 9‐Cyanoanthracene for Astrochemical Consideration

ChemPhysChem, EarlyView.
Experimental infrared absorption spectra of three protonated cyano‐substituted PAHs measured by infrared multiple photon dissociation using the free‐electron laser Free‐Electron Laser for Infrared eXperiments are studied. These spectra are compared to an emission spectrum measured by JWST, and the largest measured protonated cyano‐PAH, cyanoanthracene,

When Dihedral Angles Mask Denticity in Molecular Conductance

ChemPhysChem, EarlyView.
This study tests whether higher molecule–electrode denticity increases conductance in single‐molecule junctions. Using nonequilibrium Green's function technique in conjunction with density functional theory simulations and mechanically controlled break‐junction experiments on a tetradentate N‐heterohexacene, it is found that conductance depends mainly ...
