Thanks to the unique features of the fluorine atom and the fluorinated groups, fluorine-containing molecules are essential. Therefore, the search for new fluorinated groups as well as straightforward and original methodologies for their installation is of prime importance. Especially, the combination of organofluorine chemistry with transition metal-catalyzed C–H bond functionalization reactions offered straightforward tools to access original fluorinated scaffolds. In this context, over the last years, our group focused on the development of original methodologies to synthesize fluorine-containing molecules with a special attention to emergent fluorinated groups. The present account highlights our recent contributions to the synthesis of highly value-added fluorine-containing compounds by transition metal-catalyzed C–H bond activation.

In this paper, pressurized sample infusion electrospray ionization mass spectrometry (PSI-ESI-MS) and FTIR spectroscopy was used to investigate the mechanism of a like-Barbier cobalt-mediated one-pot transition metal-catalyzed multicomponent reaction (MCR). The use of charge-tagged aryl halides allowed for the detection of cobalt(II)-promoted hydrodehalogenation products. Although these products were also detected in the off-line ESI-MS monitoring, the ability of PSI-ESI-MS to track real-time changes in the reaction mixture composition proved cobalt(II) was responsible for the undesired transformation. The occurrence of cobalt(II)-promoted hydrodehalogenation as a side reaction in this MCR had not been considered in previous mechanistic proposals and represents an important mechanistic consideration.
