Heptafluoro-l,4-cyclohexadien-l-yl) xenon(ll) hexafluoroarsenate and (non-afluorocyclohexen-l-yl) xenon(ll) hexafluoroarsenate reacted with bromide ion in acetonitrile and formation of l-bromoheptafluoro-l,4-cyclohexadiene or 1-bromo-nonafluorocyclohexene, respectively, was established13. Similar reaction with benzene gave l-phenylheptafluoro-l,4-cyclohexadiene or 1-phenylnonafluorocyclohexene (Scheme 36). 

Since the sum of the ionic radii is known (from x-ray studies), both radii may then be evaluated. Similarly, if the S values for the argon, krypton, and xenon structures are known, the interionic distances in KC1, RbBr, and Csl may be used to calculate ionic radii for K+, Rb+, Cs4, Cl, Br, and I . The values for cesium and iodide ions must be regarded cautiously (for, as we shall see presently, the structure of the cesium halides is different from that of the other alkali halides) but the radii of the retnaining ions fit into a self-consistent system. Thus, adding from sodium fluoride (0.95 k) to R Br from rubidium bromide (1.95 A) yields a sum not greatly different from the observed interionic distance in solid sodium bromide (2.98 A). 

In spite of the presence of the type 1 part of the surface, one can frequently estimate the two-dimensional critical temperature of the phase transition, provided that the type 2 part of the surface is uniform enough to make the transition manifest. Thus we can use this procedure, for example, with the supra- and sub-critical isotherms of methane, ethane, and xenon adsorbed by the jlOOl face of sodium chloride, published by Ross and Clark (12). Using estimates of aTc from these data in Equation 4 yields a value for the surface field of F = 1.5 0.5 X 10r> e.s.u. per sq. cm. the poor precision of the result is due to the difficulty of interpolating the temperature of the critical isotherm by eye. The surface field of the jlOOj face of sodium bromide can be estimated in a similar way, using the data of Fisher and McMillan (6) for the adsorption of methane and krypton. The result for the surface field is again between 1 and 2 X 105 e.s.u. per sq. cm.

Methods based on iodine titration with thiosulfate Iodide, being a weak reduc-tant, can react with an enormous variety of oxidants to liberate an equivalent quantity of I2 that can be titrated with thiosulfate. Such oxidants include peroxides, peroxy compounds, peroxydisulfate, ozone, iron(III), chromate, selenium (as Se03 ), silver(II) oxide, xenon trioxide, iodate, and bromate. Bromide can be determined by oxidizing it to bromine, followed by extraction and determination of the bromine... 

In accordance with the observation that the anti-microbial effect of gases like nitrogen dioxide, carbon dioxide or xenon can be related to the effects of general anaesthetics, it seems natural to relate the well-knovm anti-microbial effect of cationic surfactants to local anaesthetic agents. The first type of perturbants shifts the actual transition in the direction La - whereas the second t)rpe of agent is expected to shift the transition in the opposite direction. It should be mentioned that quaternary ammonium surfactants such as cetyltrimethyl ammonium bromide in micellar solution in water were found to transform the cubic phase into the La phase [34]. 

One piece of recent chemistry of [Xe2]+ has been its reaction with bromide and iodide ions in the presence of xenon gas, which yields the excited complexes XeBr and Xel respectively (107).
