Abstract

5-Norbornene-2-nonaneacidethylester and 5-norbomene-2-hexane were synthesised by Diels-Alder reaction of cyclopentadiene and corresponding olefins. Diels-Aider reaction usually results in a mixture of endo and exo isomers. The monomers were obtained in an approximate ratio of 75:25 (endo/exo), which was determined by GC-MS and H-1-NMR-spectroscopy. Both monomers were detailed characterized using ID H-1-NMR, ID C-13-NMR, 2D (1)HJH COSY, 2D H-1-C-13 HMQC and 2D H-1-C-13 HMBC techniques.
