Processes of bonding lithium plates to other metal substrates are provided, using lithium plates preformed with a surface having indentations imposed therein, wherein that surface is placed against the substrate, which reduces the force required to achieve interface bonding.

Processes for low pressure, cold bonding of solid lithium to metal substrates

Lithium diphenylphosphide solutions in a solvent, e.g., diethoxymethane (DEM), that are more stable than when tetrahydrofuran (THF) is used as a solvent. Methods of producing them are also disclosed.

Production of lithium diphenylphosphide

Methyllithium is prepared by reacting chloromethane with a dispersion lithium metal in an aromatic organic solvent with methyltetrahydrofuran.

Process for preparing methyllithium

Tin lithium compounds of the formula RR&prime;R&Prime;SnGM&prime;, wherein R, R&prime; and R&Prime; may be the same or different and each comprises an alkyl, aryl, aralkyl or alkylaryl having from 1 to 15 carbon atoms and wherein each carbon atom may be unsubstituted or substituted, G is a substituted or unsubstituted branched, cyclic or straight chain hydrocarbon having from 1 to 20 carbon atoms, the substitutions comprising one or more aryl groups, and M&prime; is an alkali metal comprising Li, Na or K, are prepared. These compounds are useful as initiators in anionic polymerization reactions.

Hydrocarbon soluble, tin functionalized alkali metals

Lithium diorganoamide compositions are prepared in ethers with an ether to diorganoamide mole ratio of from about 2.0 to about 5.0. These compositions have enough thermal stability generally due to the addition of stabilizers that the decomposition rate for lithium diorganoamide is less than 0.20% per day. Preferred stabilizers are LiBr, LiCl, LiI or Li-tert-butoxide, or combinations thereof. A preferred diorganoamide is lithium diisopropylamide.
