Process for preparing 2,2-diphenylhexafluoropropanes |
摘要 |
2,2-diphenylhexafluoropropanes are prepared by condensation reaction of benzene or benzenes substituted with a halogen atom or atoms, a lower alkyl group or groups or a hydroxyl group or groups with hexafluoroacetone in the presence of trifluoromethane sulfonic acid. Among the 2,2-diphenylhexafluoropropanes, 2,2-diphenylhexafluoropropane and 2,2-bis(p-chlorophenyl)hexafluoropropane are novel compounds.
