실험 절차

Ferrocenaldehyde or ferrocenyl methyl ketone and allyl bromide are reacted in an ether solvent and in the presence of magnesium metal as a catalyst. The liquid portion of the reaction mixture is introduced into a silica gel column, wherein the weak acidity of the silica gel is able to dehydrate the reaction intermediate 1-ferrocenyl-3-buten-1-ol product. The column is eluted with n-hexane, and after evaporating the solvent from the eluate collected, a purified ferrocenyl-1,3-butadiene product is obtained.
