ABSTRACT:
A process for producing nornally liquid hydrocarbon solutions of lithium dialkylamides and lithium alkylenecycloimides, essentially free of ethers and by-product gaseous alkanes derived from C1-C4 alkyllithium compounds, comprising reacting lithium metal with a C.sub.5 to C.sub.12 secondary amine and an electron carrier compound containing at least five carbon atoms in a normally liquid hydrocarbon solvent.
