Abstract
The present invention provides a process for producing alkylidenenorbornenes by reacting C.sub.4 -C.sub.6 acyclic conjugated dienes with cyclopentadiene, dicyclopentadiene, or a methyl- or dimethyl-substituted derivative thereof in the presence of a catalyst derivative composed of: (A) a titanium-containing compound, and (B) at least one metallic reducing agent containing the group IA, IIA or IIIA metals in the periodic table.
