TMSCF3 as a Convenient Source of CF2=CF2 for Pentafluoroethylation, (Aryloxy)tetrafluoroethylation and Tetrafluoroethylation  Li, Lingchun; Ni, Chuanfa; Xie, Qiqiang; Hu, Mingyou; Wang Fei; Hu, Jinbo* Angewandte Chemie, International Edition 2017, DOI: 10.1002/anie.201705734.       In your own lab: The on-site generation of CF2=CF2 from TMSCF3 under mild conditions is possible with a two-chamber system and can be used for per- or polyfluoroalkylation. This study describes a convenient and safe approach for the use of CF2=CF2 in standard laboratories, and provides a new method for pentafluoroethylation.
