要旨:
Trimethylsilyl cations in a molten salt: The weakly coordinating anions [RCB11F11]− (R=H, C2H5; see structure; F green, B orange, Si gray, C black) stabilize the [Me3Si]+ cation so well that the 1H, 13C, and 29Si NMR spectroscopic parameters could be measured in the melt without using a solvent. The crystal structures and the synthesis of the solid super acids H[RCB11F11] (R=H, C2H5) are also reported.
