From gem-difluoromethyl group of 1,1,2,2-tetrafluoroethyl ether and 2,2-difluoroalkylamide, proton can be removed by potassium bis(trimethylsilyl)amide in DMF, THF or toluene. The generated nucleophiles are then condensed with benzophenones, benzaldehydes or Schiff's bases to provide new fluorinated alcohols and amines. Some interesting solvent effects are also observed.
从1,1,2,2-四氟乙基醚和2,2-二氟烷基酰胺的宝石-二氟甲基中,质子可以在DMF,THF或甲苯中被双(三甲基甲硅烷基)酰胺钾除去。然后将生成的亲核试剂与二苯甲酮,苯甲醛或席夫氏碱缩合,以提供新的氟化醇和胺。还观察到一些有趣的溶剂效果。
