Synthesis of benzyl propionate under room temperature using Brnsted acid task-specific ionic liquid as catalyst;

A new catalytic system, PdCl_2/TSILs, for catalytic oxidation of styrene to acetophenone with hydrogen peroxide was designed through the combination of PdCl_2 and task-specific ionic liquids (TSILs) of N-carboxyl-appended imidazolium cations with various anions.

The changed reaction mechanism and improved activity and stability of catalyst and high yield were always found in task-specific ionic liquid, which was a bursting branch of ionic liquid.

Herein we describe the functional ionic liquids, which are purely made of functional organic cations and functional inorganic or functional organic anions with unique properties such as wide liquid range, good solvating ability, tunable polarity, high thermal stability, nonvolatility, and so on, is a green catalyst, which can replace traditional ac.
