Notes:
The cationic transannular oligomerization of cis-cis-1,5-cyclooctadiene (1), initiated by AlEtCl2 and Al2Et3Cl3, was studied. Several cationic catalysts were examined, and the order of activities of these catalysts was found to be the following one: BF3 · OEt2 〈 AlCl3 〈 AlEtCl2 〈 Al2Et3Cl3. The number-average molecular weights of the resultant polymers are ≈ 1000 - 2000, and the softening temperature ranges 130 - 160°C. By means of NMR, IR and PC-MS spectral analyses, the structure of poly(1,5-cyclooctadiene), proposed earlier by Marvel et al., could be corroborated.
