Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy

Chemistry – A European Journal, EarlyView.
Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.

Alkyl Bismuth Cations: Synthesis, Characterization, and Application as Z‐Type Ligands

Chemistry – A European Journal, EarlyView.
Rare examples of alkyl bismuth cations [BiR2(SbF6)] are presented, including cyclopropyl ligands and a bismacyclic structure. The bismuth‐centered Lewis acids act as Z‐type ligands toward the electron‐rich platinum atom in [Pt(PCy3)2], generating a set of metal‐only Lewis pairs. The structural and spectroscopic properties of these rare types of bismuth

Insights into the Photocatalytic Arene Bromination Enabled by Cs2AgBiBr6 Microparticles

Chemistry – A European Journal, EarlyView.
A sustainable photocatalytic bromination of electron‐rich arenes is enabled by low‐toxicity Cs2AgBiBr6 double‐perovskite microparticles using HBr as an atom‐economical bromine source. Surface‐derived bromine radicals drive highly selective mono‐bromination under mild conditions.

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.
