Iron-Catalyzed, Highly Regioselective Synthesis of alpha-Aryl Carboxylic Acids from Styrene Derivatives and CO2 [PDF]
The iron-catalyzed hydrocarboxylation of aryl alkenes has been developed using a highly active bench-stable iron(II) precatalyst to give alpha-aryl carboxylic acids in excellent yields and with near-perfect regioselectivity. Using just 1 mol % FeCl2, bis(

Reductive Dehalogenation of Bromoform in Aqueous Solution
The hybrid semiconducter-macrocycle catalyst TiO2-cobalt phthalocyanine promotes the solar photolysis of aqueous bromoform under anaerobic conditions. The major decomposition products are dibromoethane and HBr. Bromomethane and methane were produced only after prolonged photolysis (30 hr).

On the Structure and Redox Behavior of Ni and Cu Single Atoms Supported on Carbon Nitride
Magnetic and electronic spectroscopies, combined with DFT, establish the MN4 binding site of Ni and Cu single atoms on carbon nitride and elucidate their redox photochemistry. Ni undergoes geometry‐preserving, reversible M2+/M+ cycling, whereas Cu collapses to an irreversible low‐coordinate Cu+ state, suppressing photocatalysis.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance
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.
