ABSTRACT:
Hydrocarbon, especially aliphatic and/or cycloaliphatic hydrocarbon, solvent solutions of complexes of n-butyllithium and ethyllithium, exemplified by (a) equimolar solutions of n-butyllithium and ethyllithium in n-hexane or cyclohexane, (b) 36 molar % n-butyllithium and 64 mole % ethyllithium in n-hexane or cyclohexane, and (c) 25 mole % n-butyllithium and 75 mole % ethyllithium in n-hexane or cyclohexane. The thermal stability of the complexes of n-butyllithium and ethyllithium in the solutions thereof in hydrocarbon solvents has been found to be outstanding. The hydrocarbon solvent solutions of said complexes, especially where said solvents are aliphatic or cycloaliphatic, have marked advantages over conventionally used hydrocarbon solvent solutions of n-butyllithium as catalysts or initiators in polymerization reactions, telomerization reactions, metalation reactions, halogen-metal interchange reactions, and in the preparation of magnesium alkyls and other organometallics.
