| The activation of C-F bonds is of particular interest because of the stability of these bonds, and the resulting need for high energy intermediates. The first reported C-F bond activation by Richmond and co-workers involved a tungsten carbonyl with a tethered perfluorobenzene ring. The mechanism of this reaction has recently been studied, with a focus on understanding the role of structural and electronic factors on the reactivity. Nanosecond time-resolved FT-IR spectroscopy was used to measure key intermediates in the pathway. Comparisons to a model system, tungsten hexacarbonyl, have been made. Finally comparison to ab initio computations shows the importance of transiently complexed solvent molecules in the reaction pathway. |
