This proposal aims to expand the scope of the reactive systems evaluated by our research group (organo- and metal-based chiral catalysis) to including more complex reactive systems as polymerization reactions and the formation of drug metabolites and degradation products. To achieve these goals, the infrared ion spectroscopy (IRMPD spectroscopy) technique developed in the framework of the…

Mass spectrometry, especially when coupled to ambient ionization sources like electrospray ionization (ESI), allows detailed chemical reaction mechanistic information to be obtained because of the great sensibility and dynamic detection range of this technique. Other orthogonal approaches to differentiate isomers, like the vibrational gas phase ion spectroscopy (ESI-MS-IRMPD) developed in…
The instrument requested consists in the coupling of a infrared tunable laser system to a 3D ion trap mass spectrometer specially modified to allow trapped ions to be irradiated by infrared photons, causing ion dissociation and allowing the acquisition of vibrational spectra of gas-phase ions. This technique, when coupled to the ion trap's ion sources, allows conformational studies of spe…

The JP2 proposal to which this request is associated consists on the application of the vibrational ion IRMPD spectroscopy and differential ion mobility (FAIMS) for the study of complex reactive systems, like polymerization reactions and formation of electrochemical (EC) reactive intermediates on the context of drug metabolism and degradation. To achieve these goals, a FAIMS device need t…
This study aims to evaluate reaction mechanisms mediated by organometallic catalysts, especially the reactions based on Ti and Pd catalysts. These reactions are not only relevant for organic synthesis and widely used in industrial pathways, but also allow experimental techniques to be developed for their evaluation by mass spectrometry, allowing the nature of the chemical species involved…

This proposal requests funding for the Ph.D. candidate to conduct predissociation ion spectroscopy and ion mobility experiments in Prof. Gert von Helden's group in the Fritz Haber Institute (Germany), so a comprehensive evaluation of reaction intermediates, a central point to the candidate thesis project, can be achieved in a way that is not possible using the techniques available in our …
The complete understanding of reaction mechanisms at the molecular level, like the cyclization reactions promoted by palladium-based catalysts, is elementary for the proposition of new catalytical systems and the synthesis of new chemical compounds. Mass spectrometry is a powerful technique to study reaction intermediates, especially when used in combination with DFT calculations and IRMP…
The undergraduation research project 2015/11769-9, to which this proposal is linked, aims to support the study of the titanium tetrapropoxide/tartrate catalytic system that is applied for the Sharpless asymmetric epoxidation, an important reaction for synthetic chemistry. The choice of this system was due to the still debated nature of the effective catalytic structure, which controls the…
