Abstract
A process for producing organometallic compositions by reacting an organohalide with a mixture of two metals; one being an alkali metal, the other being selected from magnesium, calcium, barium and zinc in a hydrocarbon solvent containing 0.5 to 2.0 moles of a Lewis Base per mole of organohalide.
Claims10
An organometallic composition comprising (1) 50 to 99 mole percent of an organometallic composition (a) of the formula RM in which R is selected from methyl, ethyl and propyl and M the metal is an alkali metal selected from lithium, sodium and potassium;
- (2) 50 to 1 mole percent of an organometallic composition (b) of the formula R.sup.1 R.sup.2 M.sup.1 in which R.sup.1 and R.sup.2 are independently selected from methyl, ethyl and propyl and M.sup.1 the metal is selected from magnesium, barium, and calcium;
- (3) a hydrocarbon solvent;
- (4) 0.05 to 2 mole equivalents of a Lewis Base selected from tetrahydrofuran and methyltetrahydrofuran per mole of organometallic composition;
- and (5) 1 to 100 mole percent of lithium halide, LiX, based on the organometallic composition.
