- Process for preparing 2,2-diphenylhexafluoropropanes
-
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.

- An efficient procedure for palladium-catalyzed reduction of aryl/enol triflates
-
An efficient procedure to deoxygenate phenols and enols via trifluoromethanesulfonates is presented. Their reduction with triethylsilane in the presence of a catalytic amount of palladium acetate and bidentate phosphine ligands such as 1,3-bis(diphenylphosphino)propane or 1,1'-bis(diphenylphosphino)ferrocene proceeds efficiently to afford a variety of aromatic, heteroaromatic, and olefinic compounds.
