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.
在促进剂存在的情况下,1,2-双(二甲基苯基硅基)四氟乙烷与少量过量的苯甲醛反应,可选择性地得到三氟乙烯基化产物--1,1,2-三氟-3-苯基丙烯-3-醇。在苯甲醛溶剂中或低温条件下,也能得到四氟乙烯化产物 2,2,3,3-四氟-1,4-二苯基丁烷-1,4-二醇。
