ABSTRACT:
An organolithium compound according to the present invention containing a cyclic amino group, has the general formula: ##STR1## wherein R.sub.1 is a divalent alkylene, an oxy- or amino-alkylene, or substituted alkylene having from 6 to about 20 carbon atoms; R.sub.2 is a linear-, branched-, or cyclo-alkylene having from about 2 to about 20 carbon atoms; and the lithium, Li, is bonded directly to a carbon atom of R.sub.2. A method of preparing an organolithium compound containing a cyclic amino group, comprising reacting a cyclic amino organo halide having the general formula ##STR2## where R.sub.1 and R.sub.2 are as above, and X is bromine or chlorine bonded directly to a carbon atom of R.sub.2, with a lithium reactant selected from lithium metal or an organolithium compound.
