| 專利名稱 | Method for the preparation of ferroceny1-1,3-butadiene | | 專利證號 | US6664409B1 | | 國別 | 美國 | | 獲證日期 | 2003-12-16 | | 專利摘要 | 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. | IPC國際分類號 | C07F001702 |
