The Ji-complexes formed between chromium(O), vanadium(O) or other transition metals, and mono- or poly-fluorobenzene show extreme sensitivity to heat and are explosive [1,2], Hexafluorobenzenenickel(O) exploded at 70°C [3], and presence of two or more fluorine substituents leads to unstable, very explosive chromium(O) complexes [1]. Apparently, the aryl fluorine atoms are quite labile, and on decomposition M—F bonds are formed very exothermically. Laboratory workers should be wary of such behaviour in any haloarenemetal Ji-complex of this type [1]. However, in later work, no indications of explosivity, or indeed of any complex formation, were seen [4]. Individually indexed compounds are ... 

A combination of xenon difluoride and water in HF was found to be a potent oxidizing agent. At ambient temperature this reagent is able to oxidize poly-fluorobenzenes and derivatives of F-cyclohexadiene-1,4. The oxidation is selective, and the C=C bond bearing Xe+ fragment does not participate in the reaction [127,128] ... 

Another recent reporP uses a set of chemically robust aryl fluorides as molecular tags. These molecules exhibit chemical shifts that range from -55 to -25 ppm relative to fluorobenzene, and are tolerant to a wide variety of chemical transformations in solid-phase chemistry. Poly-A-alkylglycines were chosen as a model system for the preparation of combinatorial...
