Fluorine ability

A scale of fluorinating ability can be drawn up by deriving the free-energy differences between component couples, (MF — MCl )/n, from HC1/HF ratios. Mixed couples can then be used to derive other values. A heat of formation of PFS was found from the reaction (76)... 

Further reports on the fluorinating ability of nitrosyl fluoride include the conversion of FN t to NF ) (61) and the fluorination of SC12 to give SF4, SF5C1, and SFfi (62). 

Sulfur tetrafluoride is very stable when compared to the lower sulfur fluorides. It can be stored at room temperature for an indeflnite period of time. It is very reactive and is valued as a selective fluorinating agent for both organic and inorganic compounds. Its remarkable fluorinating ability has been the subject of recent reviews. ... 

Alkyl bromides and iodides are converted into the corresponding fluorides in good yield with mercury(I) fluoride.31 36 Fluorinations of polyhalides are complicated by elimination reactions which give a mixture of alkenes and fluorination products. The fluorinating ability ofmercury(l) fluoride can be increased by the addition of bromine or iodine which results in the formation of mercury(II) fluorohalide.37 38 An example of the reaction of mercury(I) fluoride with simple perfluoroalkyl iodides is the formation of 2//.2//-octafluorobutane (12).39... 

In the course of a systematic study of the difluoride we have found that fluoride-ion acceptors promote its oxidative fluorinator ability. Structural evidence suggests that the important reactive species may well be XeF+ and XejFg+.t... 

Catalysis by [MnF6]2- derivatives of the thermal reaction between Xe and F2 at 120 °C has been investigated 14 the reaction is first-order in the Xe concentration and zeroth-order with respect to F2. The oxidation of xenon to [XeF]+ by [BrF6]+, which is itself generated by Kr11 cations,11 demonstrates the relative fluorinating ability of these two noble gases in the +2 state.
