Reaction Conditions

Reaction Steps

Then a sodium solution of ethanol was prepared by combining 4.3 g of sodium with 150 mL of ethanol. The solution was cooled to 0° C. and then 30 g of the phenyl alkenyl ketone was added. Then 30 mL of cyclopentadiene was slowly added to the solution and the mixture stirred for 4 hrs. Then 100 mL of water and 100 mL of pentane were added. The ethanol-water layer was then extracted twice with pentane. The organic layer was dried over filtered silica and the solvent removed in a vacuum to yield 6-phenyl, 6-(but-3-enyl)fulvene.
