Abstract: A process for preparing 5-vinyl norbornene-2 is disclosed, wherein butadiene is reacted with cyclopentadiene and/or dicyclopentadiene, with the reaction discontinued when no more than 50 mole percent of the (di)cyclopentadiene is converted. The process produces high efficiencies of converted raw materials into 5-vinyl norbornene-2. 5-vinyl norbornene-2 is a known compound having known use, such as, e.g., as a monomer suitable for polymerization with ehtylene and propylene into rubbery polymers.
