Yamaguchi, Shigehiro published the artcileEffect of Countercation Inclusion by [2.2.2]Cryptand upon Stabilization of Potassium Organofluorosilicates, Name: Difluorodiphenylsilane, the publication is Organometallics (1999), 18(15), 2851-2854, database is CAplus.
The reaction of organofluorosilanes with KF in the presence of [2.2.2]cryptand affords the corresponding organofluorosilicates with K+/[2.2.2]cryptand as the countercation. Not only diorganotrifluorosilicates, Ph2SiF3–, but also triorganodifluorosilicates, Ph3SiF2– and Ph2MeSiF2–, were obtained as stable solids. The x-ray crystal structure analyses of these silicates show that three-dimensional inclusion of the K cation by cryptand prevents an interaction between the K atom and F atoms of the silicates. A comparison of the countercation between K+/[2.2.2]cryptand and K+/18-crown-6 reveals that the inclusion of the K cation by cryptand subtly facilitates the intramol. ligand exchange, as observed by the variable-temperature 19F NMR spectra.
