Hexachloroethane → endo-Dicyclopentadiene

Participants

Reaction Steps

A 10.0 gram (75.6 mmol) amount of dicyclopentadiene was added to a 100 ml round-bottom flask. A 5.0 milligram (7.2 μmol) amount of RuClH(H2)(PCy3)2, ten equivalents of hexachloroethane, and ten equivalents of phenylacetylene were added via the addition of a 0.5 mls stock solution containing 2.5 mls of CH2Cl2, 25 mg RuClH(H2)(PCy3)2, 86 mg of hexachloroethane and 36 mg of phenylacetylene. The ring opening polymerization of dicyclopentadiene was observed slowly by a gradual thickening of the solution to a rubbery viscous material after three hours. After 24 hours, it had become a soft rubbery material.
