AI Article Synopsis
- The study investigates how various nitriles (like acetonitrile and benzonitrile) react with strong acid mixtures (HF/AsF5 or HF/SbF5) leading to the formation of protonated nitrile compounds.
- The resulting protonated products, known as nitrilium ions, were isolated as different salts (e.g., [AsF6](-), [SbF6](-), and [Sb2F11](-)).
- These nitrilium ions were analyzed and characterized using techniques such as multinuclear NMR, vibrational spectroscopy, and X-ray crystallography to understand their structural properties.
Article Abstract
The reactions of acetonitrile, propionitrile, butyronitrile, N,N-dimethylaminoacetonitrile, benzonitrile, o-tolunitrile and 1,4-dicyanobenzene with HF/AsF5 or HF/SbF5 in anhydrous HF result in protonation of the nitrile. The obtained nitrilium ions were isolated as [AsF6](-), [SbF6](-) and [Sb2F11](-) salts and characterized by multinuclear NMR and vibrational spectroscopy, and their X-ray crystal structures.
