A New Spin on Photocatalysis: Vortex Fluidic‐Driven Photooxidations Enabled by Solution‐Processable Microporous Polymers

Chemistry – A European Journal, EarlyView.
Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

Controlled Formation and Unusual Reactivity of Cyanohexatriyne (HC7N), a Synthetically Challenging Interstellar Cyanopolyyne

Chemistry – A European Journal, EarlyView.
First controlled formation of cyanohexatriyne (HC7N) is achieved using a cobalt–alkyne masking strategy that overcomes the intrinsic instability of nitrile‐substituted polyynes. The approach enables spectroscopic validation of HC7N and reveals its pronounced electrophilicity through a selective conjugate addition with diethylamine.

Unbiased Reaction Network Exploration of C–C Coupling in Methane Dehydroaromatization Over Mo‐ZSM‐5

Chemistry – A European Journal, EarlyView.
Automated reaction route mapping reveals distinct methane coupling pathways over mono‐ and dinuclear Mo carbide species in ZSM‐5. Mononuclear [MoC]2+ selectively forms desorbable C2H4, whereas dinuclear [Mo2C2]2+ promotes strongly adsorbed C3/C4 intermediates linked to coke formation.

Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

Chemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Synthesis of Tris(indol‐3‐yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two‐Step Construction of π‐Conjugated Systems

Chemistry – A European Journal, EarlyView.
Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...
