Lithium nitrite

Lithium nitrite (H2O) [13568-33-7] M 71.0. Crystd from water by cooling from room temperature. [Pg.436]

The synthesis of aliphatic nitro compounds from the reaction of alkyl halides with alkali metal nitrites was discovered by Kornblum and co-workers and is known as the modified Victor Meyer reaction or the Kornblum modification. The choice of solvent in these reactions is crucial when sodium nitrite is used as the nitrite soiuce. Both alkyl halide and nitrite anion must be in solution to react, and the higher the concentration of nitrite anion, the faster the reaction. For this reason, both DMF and DMSO are widely used as solvents, with both able to dissolve appreciable amounts of sodium nitrite. Although sodium nitrite is more soluble in DMSO than DMF the former can react with some halide substrates.Urea is occasionally added to DMF solutions of sodium nitrite to increase the solubility of this salt and hence increase reaction rates. Other alkali metal nitrites can be used in these reactions, like lithium nitrite,which is more soluble in DMF than sodium nitrite but is also less widely available. [Pg.9]

Lithium nitrite, LiN02.—The monohydrate, LiN02,H20, is obtained by the interaction of lithium chloride and silver nitrite,7 and also by that of lithium sulphate and barium nitrite.8 It forms colourless, deliquescent needles, very soluble in water. At 0° C. its density is 1 615,9 and between 21° C. and 31° C. 1 671. Its molecular volume is 63-44.10 Under the influence of sunlight it decomposes, with formation of the red nitride. Oswald11 also prepared a colourless, deliquescent semihydrate, and proved that the colourless anhydrous salt becomes hydrated through the action of the moisture of the atmosphere. [Pg.72]
