Abstract
Hydrocarbon, especially aliphatic and/or cycloaliphatic hydrocarbon, solvent solutions of complexes of isopropyllithium and ethyllithium, exemplified by (a) equimolar solutions of isopropyllithium and ethyllithium in n-hexane or cyclohexane, and (b) 25 mole % isopropyllithium and 75 mole % ethyllithium in n-hexane or cyclohexane. The hydrocarbon solvent solutions of said complexes, especially where said solvents are aliphatic or cycloaliphatic, have various advantages over conventionally used hydrocarbon solvent solutions of isopropyllithium 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.
