Abstract
Cyclopentadienyl derivatives are deprotonated by a process whereby the cyclopentadienyl derivatives are reacted with a Grignard reagent in an inert solvent which contains from about 0.5 to 1.5 equivalents per equivalent of cyclopentadienyl derivative of a cyclic ether or an acyclic polyether, so as to form a dianionic salt of said cyclopentadienyl derivative.
