摘要：

The strongest metal-free base is the cation 1, which can be prepared in a one-pot procedure from PCl5, NH4Cl, Me2NH, and NaBF4. Anion exchange affords 1-F, which mediates in the alkylation of an anionic allylic species produced from allyltrimethylsilane; furthermore, the unsolvated floride ion is an excellent proton-selective base for E2 eliminations.
