Multiple C-F bond activation: Remarkable 4 to 4 bond-breaking/bond-making reactions of Nb+ with hexafluoro- and tetrafluorobenzene

摘要

Mass spectrometric reaction rate measurements are reported that show the remarkable occurrence of the breaking of four C-F bonds and the formation of four new Nb+-F bonds in gas-phase collisions of Nb+ with hexafluoro- and tetrafluorobenzene. A mechanism involving sequential intramolecular fluorine pick-up is proposed. [References: 21]
