A dry, sealed, and evacuated stainless steel bomb, cooled via a duty ice/acetone bath, was charged with chilled cycloalkene
(5 g, ~30 mmol) and Wilkinson's catalyst (0.15 g, 0.16 mmol) and purged with nitrogen.
The further monomer(s) is or are selected from the group of unsaturated compounds, which can be polymerized cationically, which includes aromatics and/or unsaturated terpenes and/or alkenes and/or cycloalkenes
In Figure 3 the peaks are attributed to cycloalkenes
(L, [r.sub.t] 10.3 min), cyclopentyl-ethanone (M, [r.sub.t] 10.6 min), oxygen-containing compounds (unmarked, [r.sub.t] 10.7-11.8 min), for example, cyclohexanone and alcohols.
It might react with dienes, alkenes and cycloalkenes
, with heterocyclic dienophiles like N-methylpyrrole and indole derivatives, with alkynes, enamines and other compounds.
