五元环氟化物的合成及应用

The synthetic routes for a series of five-membered ring fluorides by using dicyclopentadiene (DCPD), hexachlorocyclopentadiene (HCCPD) or octachlorocyclopentene (OCP) as starting materials are reviewed, including 1, 2-dichlorohexafluorocyclopentene (F6-12), 1, 3-dichlorohexafluorocyclopentene (F6-13), 1-chlorohepta-fluorocyclopentene (F7-1), 1, 1, 2, 2, 3, 3, 4-heptafluorocyclopentane (F7A), 1, 1, 2, 2, 3, 3-hexafluorocyclopentane (F6A), cis-1, 1, 2, 2, 3, 3, 4, 5-octafluorocyclopentane (cis-F8A), octafluorocyclopentene (F8E), 3, 3, 4, 4, 5, 5-hexafluorocyclopentene (F6E), 1, 3, 3, 4, 4, 5, 5-heptafluorocyclopentene (F7E) and the application of five-membered ring fluorides in electronic cleaning, electronic etching, and synthesis of electronic fluoride solutions. It is proposed that the synthesis research of five-membered ring fluorides mainly focus on the development of novel synthetic routes, catalysts with high activity and no harm to human health, and green manufacturing. Furthermore, the application research focus on the development of the electronic grade products and the downstream products of five-membered ring fluorides.
