Procedure
6-Phenyl-6-oxohexanoylferrocene (5.61g; 15 mmole) in sodium dried dioxane (150 ml) was heated under reflux with sodium hydride (0.72g; 30 m mole) for 3 hr. The mixture was cooled and treated carefully with water (200 ml) when a brown solid precipitated, which was filtered off to yield 4.3g (76%) of nearly pure 1-ferrocenoyl-2-phenylcyclopentene. An analytical sample (3.7g; 69%) was obtained by one recrystallization from cyclohexane. mp 163°-164°.
