Abstract
Alkali metal organic compounds including perlithiated organic compounds are produced by contacting an organic compound having a carbon to hydrogen bond or a carbon to halogen bond in its molecular structure or carbon vapor with a vaporous alkali metal under dry conditions and in the absence of a gas that reacts with the alkali metal other than the organic compound. The alkali metal is activated such as thermally or by being passed through a radio frequency field so that it has sufficient energy to break at least one of the bonds. Perlithiated compounds are formed from alkanes, alkenes, cycloalkanes and aromatic hydrocarbons.
Claims33
A process for forming an alkali metal organic compound which comprises contacting an organic reactant selected from the group consisting of carbon vapor and an organic compound having a carbon to hydrogen bond or a carbon to halogen bond with a vaporous alkali metal under dry conditions and in the substantial absence of a gas that reacts with the alkali metal other than the organic reactant, said alkali metal having sufficient energy to react with the carbon vapor or to break at least one of said bonds.
