Title
Efficient synthesis of benzophenone derivatives in Lewis acid ionic liquids
Abstract

Benzophenone and its derivatives were prepared via Friedel–Crafts acylation reactions using ionic liquids (ILs) of BmimCl–FeCl3, BmimCl–AlCl3 and BmimCl–ZnCl2 as dual catalyst–solvent. Among them, BmimCl–FeCl3 showed much higher catalytic activity than that observed for the other two ILs, and in conventional organic solvents. In these reaction systems, good to excellent yields (up to 97%) of acylation products were obtained in a short reaction time. This method features high yield, a simple product isolation procedure, ILs reusability and reduced waste discharge, thus rendering this catalytic system both efficient and environmentally friendly.
