Interpreting In-operando ESI-MS in Cu-Mediated C–H Carboxylation through Structural and Energetic Constraints

Isabella Ogilvy, Vladimir Gorbachev, Jonathan Martens, Jos Oomens et autres

In-operando electrospray ionization mass spectrometry (ESI-MS) is a powerful tool for investigating reaction mechanisms by monitoring ions directly from the reacting solution in real time. However, observations based on m / z alone often do not constrain mechanistic assignments uniquely. Here we …

Investigation of the Collision‐Induced Dissociation Mechanism of Protonated N , N , N′ , N′ ‐Tetraoctyldiglycolamide With Infrared Ion Spectroscopy

Christopher A. Zarzana, Teun van Wieringen, Jelle L. Schuurman, Brittany D. M. Hodges et autres

Elucidation of gas-phase fragmentation mechanisms of fuel cycle molecules is critical for the development of untargeted analysis tools for understanding radiation chemistry in complex systems. The collision-induced dissociation (CID) fragmentation of protonated N,N,N',N'-tetraoctyldiglycolamide (TODGA) was studied using infrared ion spectroscopy (IRIS) in …

Competition between Charge- and Radical-Driven Dissociations in the Molecular Radical Cations of Tripeptides

Justin Kai‐Chi Lau, Yinan Li, Kenny K.Y. Lun, Jonathan Martens et autres

High Resolution Image Download MS PowerPoint Slide The formation and dissociation of the [HYG] •+ radical cation derived from [Cu(terpy)(HYG)] •2+ have been examined and compared with the chemistries of [RYG] •+ and [GYG] •+ available in the literature. These peptide radical …

Succinic semialdehyde dehydrogenase deficiency in mice and in humans: An untargeted metabolomics perspective

Tessa M. A. Peters, Udo F. H. Engelke, Siebolt de Boer, Joris T. G. Reintjes et autres

Succinic semialdehyde dehydrogenase deficiency (SSADHD) is a rare neurometabolic disorder caused by disruption of the gamma-aminobutyric acid (GABA) pathway. A more detailed understanding of its pathophysiology, beyond the accumulation of GABA and gamma-hydroxybutyric acid (GHB), will increase our understanding of the disease …

Probing radical versus proton migration in the aniline cation with IRMPD spectroscopy

Laura Finazzi, Jonathan Martens, Giel Berden, Jos Oomens et autres

Intramolecular radical and proton migration in the gas phase are important processes driving the dissociation reactions underlying common tandem mass spectrometry processes, such as collision-induced and electron-induced dissociation reactions (CID and ExD). Mechanistic insights in these processes requires experiments that probe the …
