1,2-Bis(dimethylphenylsilyl)tetrafluoroethane. Application to the trifluorovinylation and tetrafluoroethylenation of carbonyl compounds

Article abstract of DOI:10.1246/cl.1997.787

The reaction of 1,2-bis(dimethylphenylsilyl)tetrafluoroethane with a small excess of benzaldehyde in the presence of the promoter gave the trifluorovinylated product, 1,1,2-trifluoro-3-phenylpropen-3-ol, selectively. The tetrafluoroethylenated product, 2,2,3,3-tetrafluoro-1,4-diphenylbutane-1,4-diol, was also obtained in benzaldehyde solvent or at low temperatures.
