Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

Chemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Bis(trifluoromethyl)disulfide and the EtP4 Phosphazene Base—Formation of a Bench‐Stable [EtP4SCF3]+[SCF3]− Salt

Chemistry – A European Journal, EarlyView.
The synthesis of a bench‐stable trifluoromethylthiolate‐substituted phosphazenium salt is reported. Reaction of bis(trifluoromethyl)disulfide with the EtP4 phosphazene base furnishes this salt in quantitative yield. The compound features a unique trifluoromethylthiolate‐iminium motif and allows for functionalization of both trifluoromethylthiolate ...

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

Chemistry – A European Journal, EarlyView.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Accessing Sn≥2 States of a TADF Emitter by Femtosecond NIR Spectroscopy

Chemistry – A European Journal, EarlyView.
The depicted thermally activated delayed fluorescence (TADF) emitter was studied by femtosecond near‐infrared (NIR) spectroscopy. A prominent NIR transition was shown to be strongly solvent‐dependent, with implication for intersystem crossing in the compound.
