General description

Bicyclo[2.2.1]hept-2-ene is a cyclic olefin used in the transition metal-catalyzed dimerization of alkene.

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.

Application

Bicyclo[2.2.1]hept-2-ene may be used in the preparation of cis,exo-2,3-diarylsubstituted bicyclo[2.2.1]heptanes or bicyclo [2.2.1] hept-2-enes.

The oligomers of constrained cis-exo-beta-norbornene amino acid were synthesised and characterised by extensive NMR, CD, IR and MD studies. The results showed the formation of both right and left handed consecutive 6-membered hydrogen-bonded strands for [2S,3R] and [2R,3S] enantiomers, respectively.

Palladium complexes bearing monodentate and bidentate phosphine ligands (1-7) were synthesised and used as catalyst precursors in the methoxycarbonylation of norbornene. The catalytic systems bearing ligands 1, 3 and 4 afforded excellent conversions (>99%) and selectivity of the ester (>99%).
