Wacker Oxidation of Trisubstituted Alkenes: Pd(II)‐Catalyzed Oxidative Ring Expansion of Exocyclic α,β‐Unsaturated Carbonyl to 2‐Fluoro‐1,3‐Dicarbonyl Compounds

Jieping Zhu, Vincent Léon Norbert Goëlo

The Wacker oxidation is a powerful synthetic method widely employed for the transformation of monosubstituted alkenes into methyl ketones. Its substrate scope has progressively expanded to include internal disubstituted and, more recently, gem‐disubstitute ...

Naphthalene-Based Polymers as Catalytic Supports for Suzuki Cross-Coupling

Lioubov Kiwi

In this work, for the first time, naphthalene (NA)-based polymers were synthesized by one-stage Friedel-Crafts crosslinking. The influence of NA functionalization by -OH, -SO3H, and -NO2 groups on the polymers' porosity and distribution of the catalyticall ...

Carbonized wood impregnated with bimetallic nanoparticles as a monolithic continuous-flow microreactor for the reduction of 4-nitrophenol

Qingtong Zhang, Paul Joseph Dyson, Zhaofu Fei, Rosemarie Janet Somerville

Porous monolithic microreactors show great promise in catalytic applications, but are usually based on non-renewable materials. Herein, we demonstrate a Ni/Au nanoparticle-decorated carbonized wood (Ni/Au-CW) monolithic membrane microreactor for the effici ...

Reduction of PdO/Al2O3 in Liquid Cyclohexane Followed In Situ by ATR-IR, High-Energy XRD, and XAS

Oliver Kröcher, Davide Ferri, Thibault Xavier Florian Fovanna

Supported Pd-based catalysts used in heterogeneously catalyzed liquid phase processes often undergo an activation step through reduction of the oxide phase or of the oxidic passivation layer prior to reaction. An oxidized Pd/Al2O3 catalyst was reduced by u ...

Substantial decrease in CO2 emissions from Chinese inland waters due to global change

Tom Ian Battin

Carbon dioxide (CO2) evasion from inland waters is an important component of the global carbon cycle. However, it remains unknown how global change affects CO2 emissions over longer time scales. Here, we present seasonal and annual fluxes of CO2 emissions ...
