Synthesis of Functional Bis(pentafluoroethyl)silanes (C2F5)2SiX2, with X=H, F, Cl, Br, OPh, and O2CCF3
As recently shown, the introduction of pentafluoroethyl functionalities into silicon compounds is of general interest due to an enhanced Lewis acidity of the resulting species. By this means, the synthesis of previously inaccessible hypervalent silicon de
