摘要: A new method for the on-site preparation of tetrafluoroethylene (TFE) and a procedure its efficient use in pentafluoroethylation by fluoride addition were developed using simple two-chamber system. The TFE was accomplished dimerization difluorocarbene derived from (trifluoromethyl)trimethylsilane (TMSCF3) under mild conditions. Other fluoroalkylation reactions, such as (aryloxy)tetrafluoroethylation tetrafluoroethylation processes, also achieved similar approach. This work not only demonstrates convenient safe approach generation academic laboratories, but provides strategy pentafluoroethylation.
