Description

1-Butylpyridinium bis(trifluoromethanesulfonyl)imide is a bench-stable, moisture-tolerant ionic liquid featuring a pyridinium cation paired with a bulky, electron-deficient anion. This combination delivers high thermal resilience and low volatility, enabling its use in electrochemical applications where stability and conductivity are critical.

Application

1-Butylpyridinium bis(trifluoromethanesulfonyl)imide serves as a thermally stable, bench-ready ionic liquid with excellent solubility for polar and nonpolar substrates. It functions as a versatile reaction medium and catalyst support in cross-coupling, C–H activation, and electrochemical transformations. The pyridinium cation provides moderate polarity and enhanced stability under ambient conditions, while the bis(trifluoromethanesulfonyl)imide anion ensures high conductivity and low hygroscopicity. Its robustness enables straightforward purification and compatibility with standard synthetic workflows.
