Lithium Chloride. Of the metal haUdes, calcium bromide [7789-41-5] CaBr2, ziac chloride [7646-85-7] ZnCl2, CaCl2, and lithium chloride [7447-41-8] LiCl, (Class 1, nonregenerative) are the most effective for water removal (4). AH are available ia the form of dehquescent crystals. The hydrates of LiCl are LiCl-nH2 O, where n = 1, 2, or 3. Lithium chloride solutions are more stable ia air and less corrosive than the other metal haUdes. The high solubihty of lithium carbonate [554-13-2] Li2C02, usually eliminates scale formation problems (see LiTHlUM COMPOUNDS). 

According to the Marcus theory [64] for outer-sphere reactions, there is good correlation between the heterogeneous (electrode) and homogeneous (solution) rate constants. This is the theoretical basis for the proposed use of hydrated-electron rate constants (ke) as a criterion for the reactivity of an electrolyte component towards lithium or any electrode at lithium potential. Table 1 shows rate-constant values for selected materials that are relevant to SE1 formation and to lithium batteries. Although many important materials are missing (such as PC, EC, diethyl carbonate (DEC), LiPF6, etc.), much can be learned from a careful study of this table (and its sources). 

Fluonnated ylides have also been prepared in such a way that fluorine is incorporated at the carbon p to the carbamomc carbon Various fluoroalkyl iodides were heated with tnphenylphosphine in the absence of solvent to form the necessary phosphonium salts Direct deprotonation with butyllithium or lithium dusopropy-lamide did not lead to y hde formation, rather, deprotonation was accompanied by loss of fluonde ion However deprotonation with hydrated potassium carbonate in dioxane was successful and resulted in fluoroolefin yields of45-80% [59] (equation 54) p-Fluorinated ylides may also be prepared by the reaction of an isopropyli-denetnphenylphosphine yhde with a perfluoroalkanoyl anhydride The intermediate acyl phosphonium salt can undergo further reaction with methylene tnphenylphosphorane and phenyllithium to form a new ylide, which can then be used in a Wittig olefination procedure [60] (equation 55) or can react with a nucleophile [61] such as an acetylide to form a fluonnated enyne [62] (equation 56)... 

A large number of compounds used as catalysts in acid-ion lactam polymerization are known. These include alkalis, alkali-earth metals, hydrates, Grignard reagents, lithium oxide, various hydroxides and carbonates, sulfates, halides, sodium zincate, alkaline salts of different acids, i.e., compounds that cause the formation of lactam acid ion in the reactive medium. The mechanism of polymerization in the presence of sodium-lactam- salt compounds is largely known. 

Lithium Ion.—The colourless univalent lithium ion, Li, is characterized by the formation of salts of slight solubility with the anions of carbonic, hydrofluoric, and phosphoric acid, a distinction from the ions of the other alkali-metals, and an indication of the smaller electro-affinity of the lithium ion.12 The comparatively low electroaffinity corresponds with that of strontium, and is associated with the power of the lithium salts to form complexes with ammonia in aqueous solution, and with water to yield various crystalline hydrates. In solution in...
