| 專利摘要 | Ferrocenecarbonyl and toluene 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 ferrocenyl alcohol product. The column is eluted with ethyl acetate/n-hexane, and after evaporating the solvent from the eluate collected, a purified ferrocenyl substituted styrene is obtained. |
