Alkali metal fluorides reduction

As can be seen from Fig. 10, the Auger M line intensity becomes, through the mode 32, large for large ROR probability or for small AE defined in Fig. 2. This leads, in the first approximation, to reduction in the fluorescence yield Yxi and then also reduction in the intensity ratio of Xl/XO as shown in Fig. 11, though the fluorescence yield is, strictly speaking, a function both of Auger and X-ray yields. Thus chemical bond effects in the satellite intensities of the XI lines in the F Ka fluorescent X-ray spectra emitted from the alkali-metal fluorides have now successfully been explained. 

The claim that attack on perfluoronitroso-compounds by carbanions generated from alkali-metal fluorides and fluoro-olefins in aprotic solvents yields nitrones has been withdrawn following the discovery that reduction (NaBBU-DMF) of the... 

Metallothermic reduction of an actinide halide was the first method applied to the preparation of an actinide metal. Initially, actinide chlorides were reduced by alkali metals, but then actinide fluorides, which are much less hygroscopic than the chlorides, were more...

At a platinum electrode, highly purified FLINAK has a voltammetric window extending from about +1.5 to -2.0 V vs. the nickel reference electrode [7]. The positive limits of the alkali halide melts discussed herein arise from the oxidation of halide ions, whereas the negative limits are due to reduction of the alkali metal ions. Because chloride ion is substantially easier to oxidize than fluoride ion, the potential window of the LiCl-KCl melt is approximately 1.5 V smaller than that for FLINAK. 

From a synthetic objective it is unfortunate that attempts to produce the dianion of OFCOT by various reduction procedures have not resulted in a stable dianion. Although the organic decomposition products resulting from reduction by alkali metals or sodium naphthalenide are unknown, fluoride ion is produced (126). However, the nine-7t-electron radical anion has been produced at low temperatures by y irradiation of OFCOT, and electron spin resonance (ESR) spectroscopy indicates that it possesses the anticipated planar delocalized D8b structure 55 (127). The unavailability of the dianion... 

Srj I reactions can be initiated by photochemical excitation, electrochemical reduction, and solvated electrons (alkali metal in ammonia). In some cases, spontaneous thermal initiation can also take place. The leaving group, X , is often a halide—frequently bromide or iodide, never fluoride. The nucleophile, Y , is commonly a nitroalkane anion (5-25) or another anion such as thiolate (RS ), phenolate (PhO ), or various enolates. 

In order to accomplish a total dehalogenation to hydrocarbons, dissolving metal reductions are most commonly employed. Cyclopropyl chlorides and bromides are satisfactorily reduced by alkali metal in alcohoF or in liquid ammonia. However, the fluorides are usually resistant to the hydrogenolysis. gem-Difluorides have been...
