C-C bond activation enabled by dyotropic rearrangement of Pd(iv) species

Qian Wang, Jieping Zhu, Hua Wu, Jian Cao

The weak carbon-metal bond combined with the kinetic inertness of the carbon-carbon bond renders metal-catalysed C-C bond activation to be highly challenging. Most of the reported C-C bond activation methodologies involve strain-releasing cleavage of small ...

A catalytically active [Mn]-hydrogenase incorporating a non-native metal cofactor

Xile Hu, Farzaneh Fadaei Tirani, Matthew Wodrich, Huijie Pan

Nature carefully selects specific metal ions for incorporation into the enzymes that catalyse the chemical reactions necessary for life. Hydrogenases, enzymes that activate molecular H-2, exclusively utilize Ni and Fe in [NiFe]-, [FeFe]- and [Fe]-hydrogean ...

Mechanistic study of the photo‐generation of hydrogen by decamethylruthenocene

Hubert Girault, Pekka Eero Peljo, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon, Laurent Alexis Clément Vannay, Sunny Isaïe Maye, Lucie Josette Renée Rivier

Hydrogen evolution by decamethylruthenocene (Cp*2RuII) was studied in detail highlighting that metallocenes are capable of photo‐reducing hydrogen without the need of an additional sensitizer. Electrochemical, gas chromatographic and spectroscopic (UV/vis, ...

Mechanism and Kinetics of Propane Dehydrogenation and Cracking over Ga/H-MFI Prepared via Vapor-Phase Exchange of H-MFI with GaCI3

Matthieu Bondil

In this study, the mechanism and kinetics of C3H8 dehydrogenation and cracking are examined over Ga/H-MFI catalysts prepared via vapor-phase exchange of H-MFI with GaCl3. The present study demonstrates that GaH cations are the active centers for C3H8 ...

Water-assisted oxygen activation during gold-catalyzed formic acid decomposition under SCR-relevant conditions

Davide Ferri, Oliver Kröcher

Owing to the problems associated with the use of urea as an ammonia precursor compound in the selective catalytic reduction process in automobiles, alternative compounds such as ammonium formate, methanamide, and guanidinium formate have been suggested as ...

On the Viability of Heterolytic Peptide N-Calpha Bond Cleavage in Electron Capture and Transfer Dissociation Mass Spectrometry

Yury Tsybin, Matthew Wodrich, Konstantin Zhurov

While frequently employed as an experimental technique, the mechanistic picture surrounding the gas-phase dissociation of peptides carrying multiple positive charges during electron capture and electron transfer dissociation tandem mass spectrometry remain ...

Ping-Pong Protons: How Hydrogen Bonding Networks Facilitate Heterolytic Bond Cleavages in Peptide Radical Cations

Yury Tsybin, Matthew Wodrich, Konstantin Zhurov

Electron capture and electron transfer dissociation (ECD/ETD) tandem mass spectrometry (MS/MS) are commonly employed techniques for biomolecular analysis. The ECD/ETD process predominately cleaves N-C-alpha peptide backbone bonds, leading to primary sequen ...

Soudure par interdiffusion dans les systèmes Au-In et In-Ni

Léa Deillon

Hermiticity is an essential requirement of a MEMS package for a device to work properly. Hermeticity also must be preserved during the operations following packaging, during which the package bond should not remelt. Bonding temperature is limited however t ...

Synthesis and Properties of Molecular Nanostructures on Surfaces

Nasiba Abdurakhmanova

One central aim of nanotechnology is the creation and exploitation of nanostructured materials with pre-programmed architecture and properties. The fabrication of functional nanostructures relies on versatile protocols of synthetic chemistry enabling the p ...

Theoretical Studies of the Reductive C-S Bond Cleavage in Complexes of the Form [M(9S3)2]2+ (M = Re, Tc, and Ru; 9S3 = 1,4,7-Trithiacyclononane)

Ursula Röthlisberger

We have applied D. Functional Theory (DFT) at the generalized gradient approxn. (GGA) level to investigate the C-S bond cleavage in hexathioether complexes of the form [M(9S3)2]n+ (with 9S3 = 1,4,7-trithiacyclononane and M = Re, Tc; n = 1, 2; as well as M ...
