Fluoromethane reaction mechanism

Tris(fluorosulfuroyl)fluoromethane (329) reacted with bis(diethylamido)benzyl phosphite to yield an intermediate (330) which extruded a molecule of SO2 to give as final product the bis(fluorosulfonyl) compound (331). The kinetics and mechanism of the reaction of fluorinated tricoordinate phosphorus compounds (332) and aryl 2,2,2-trifluoroethyl sulfenates (333) have been reviewed. ... 

DFT calculations for the activation of fluoromethane and fluorobenzene at Ce and Ho have been performed revealing a harpoon-type mechanism for the metal-mediated fluoride abstraction.The reactions of the lanthanoid cations La Ce, Pr, and Yb with fluoromethane have also been investigated by DFT calculations. After coordination of Ln, electron transfer from Ln to fluoromethane takes place, followed by formation of LnF and a methyl radical. Mass spectrometric investigations which show gas-phase collisions of Nb with hexafluoro- and tetrafluorobenzene have been reported. The reaetions involve the transfer of four fluorine atoms to Nb. A systematic study on the reactivity of transition metal eations toward hexafluorobenzene in the gas phase has been performed by inductively coupled plasma (ICP) tandem mass spectrometry.Multiple fluorine atom abstraction dominates the chemistry observed for early transition metals, while association of hexafluorobenzene to the metal cation has been found for late transition metals. 

Hie formation of CH F and CF F following ener tlc F atomic substitution reactions in fluorinated methanes (71-75) and ethanes 60. 66) has been well documented. Lindner and Pauwels obtained direct evidence for C0F F production in unpublished recoil F experiments with fluoromethanes (7. 75). Although CF F was identified as the C0F F precursor through competitive experiments with C3F6 scavenger, the detailed mechanism for process 28 was not established.
