Preparation
Preparative Methods of N-Ethylacetonitrilium Tetrafluoroborate: this salt can be prepared by N-alkylation of Acetonitrile with Triethyloxonium
Tetrafluoroborate (eq 1),
[2] or by C-alkylation of isocyanides.
[1] The treatment of O,O,O-triethyl phosphorothioate
with equimolar amounts of Nitrosonium Tetrafluoroborate in anhydrous acetonitrile gave the Nethylacetonitrilium ion in moderate yield (eq 2).
