Solution-based Cu+ transient species mediate the reconstruction of copper electrocatalysts for CO2 reduction

Raffaella Buonsanti, Anna Loiudice, Petru Pasquale Albertini, Jan Vávra, Gaétan Philippe Louis Ramona

Understanding metal surface reconstruction is of the utmost importance in electrocatalysis, as this phenomenon directly affects the nature of available active sites. However, its dynamic nature renders surface reconstruction notoriously difficult to study. ...

Tandem Hydroformylation-Aldol Condensation Reaction Enabled by Zn-MOF-74

Berend Smit, Daniele Ongari

The tandem hydroformylation-aldol condensation (tandem HF-AC) reaction offers an efficient synthetic route to the synthesis of industrially relevant products. The addition of Zn-MOF-74 to the cobalt-catalyzed hydroformylation of 1-hexene enables tandem HF- ...

Improving time-resolution and sensitivity of in situ X-ray photoelectron spectroscopy of a powder catalyst by modulated excitation

Davide Ferri, Oliver Kröcher, Filippo Buttignol

Ambient pressure X-ray photoelectron spectroscopy (APXPS) is a powerful tool to characterize the surface structure of heterogeneous catalysts in situ. In order to improve the time resolution and the signal-to-noise (S/N) ratio of photoemission spectra, we ...

Simultaneous Generation of Methyl Esters and CO in Lignin Transformation

Paul Joseph Dyson, Mingyang Liu

Lignin is an abundant renewable carbon source. Due to its complex structure, utilization of lignin is very challenging. Herein, we describe an efficient strategy for the simultaneous utilization of lignin, in which the methoxy groups in lignin react with c ...

Asymmetric (CpRh)-Rh-x(III)-Catalyzed Acrylic Acid C-H Functionalization with Allenes Provides Chiral gamma-Lactones

Nicolai Cramer, Shouguo Wang

A chiral cyclopentadienyl (Cp-x) ligand featuring the semi-saturated H8-binaphthyl backbone as the chiral element was developed. Its application potential was demonstrated by (CpRhIII)-Rh-x-catalyzed C-H bond functionalization of acryl acids and allenes, e ...

Deoxygenative trifluoromethylthiolation of carboxylic acids

Xile Hu, Runze Mao, Srikrishna Bera, Alexis Baptiste Cheseaux

Here we describe a deoxygenative trifluoromethylthiolation method that yields trifluoromethyl thioesters from readily available carboxylic acids. The method is built upon an "umpolung" strategy where triphenylphosphine is used to first activate an electrop ...

Expedited Screening of Active and Regioselective Catalysts for the Hydroformylation Reaction

Matthew Wodrich, Michael Markus Busch

The discovery of new homogeneous catalysts that preferentially form one product over another in regio- or enantioselective chemical reactions has traditionally been the province of experimental chemists. Today, computational-based approaches have carved an ...

Selectivity Control in Palladium-Catalyzed Alcohol Oxidation through Selective Blocking of Active Sites

Davide Ferri, Oliver Kröcher, Di Wang

Stabilized metal nanoparticles (NPs) have received wide interest in a number of liquid-phase catalytic transformations, but the role of the capping/protective agent is still debated. Operando attenuated total reflection infrared (ATR-IR) spectroscopy enabl ...

Ketenimines from Isocyanides and Allyl Carbonates: Palladium-Catalyzed Synthesis of β,γ-Unsaturated Amides and Tetrazoles

Qian Wang, Jieping Zhu, Mathias Mamboury, Guanyinsheng Qiu

The reaction of allyl ethyl carbonates with isocyanides in the presence of a catalytic amount of Pd(OAc)2 provided ketenimines through b-hydride elimination of the allyl imidoylpalladium intermediates. The insertion of the isocyanide into the p-allyl Pd co ...
