Norbornene Usage And Synthesis

Chemical Properties	white crystalline mass
Uses	Norbornene is used as a monomer and as an intermediate in organic synthesis. It is also used to prepare pharmaceutical intermediates and specialty fragrances. It reacts with ethylene to get cyclic olefin copolymer. Further, it is used in transition metal catalysis to affect migration of electrophilic transition metals. It acts as a monomer in ring-opening metathesis polymerizations with the Grubbs' catalyst. Its polymer, polynorbornene is used in the rubber industry for anti-vibration, anti-impact in personal protective equipment and grip improvement in toy tires, racing tires and transmission system.
Definition	ChEBI: Norbornene is a bridged compound that is cyclohexane with a methylene bridge between carbons 1 and 4 and a double bond at position 2. It is a bridged compound, a carbobicyclic compound and a cyclic olefin.
General Description	The vinylic polymerization of bicyclo[2.2.1]hept-2-ene (norbornene) with Co(II) compounds and the metallocene [η⁵-(C₅Me₅)Co-η²-Cl]₂, in chlorobenzene activated with methylaluminoxane (MAO) has been reported. Co(II) catalyzed polymerization of bicyclo[2.2.1]hept-2-ene in the presence of ethene has been reported.
Flammability and Explosibility	Non flammable
Purification Methods	Reflux it over Na, and distil it [Gilliom & Grubbs J Am Chem Soc 108 733 1986]. It has also been purified by sublimation in vacuo onto an ice-cold finger. [Woon et al. J Am Chem Soc 108 7990 1986, Beilstein 5 IV 394.]
