Abstract

A new route to prepare tricyclo[5.2.1.0 2,6]deca-2,4-diene (isodicyclopentadiene) was developed. This new route passes through a brominated (5-bromotricyclo[5.2.1.0 2,6]dec-3-ene) derivative obtained from tricycle[5.2.1.0 2,6]dec-3-ene (8,9-dihydrodicyclopentadiene) and NBS with a good yield. The complete assignment of protons and carbons on nuclear magnetic resonance spectra was done for dicyclopentadiene and the chemically transformed compounds by 2D NMR techniques. © 2007 Elsevier Ltd.
