Direct Oxidative Conversion of Benzoyl Chlorides to 2-Imidazoles Using Heteropolyacids

Abstract

The reaction of benzoyl chlorides with ethylenediamine in the presence of catalytic amounts of Keggin-type heteropolyacids led to oxidative conversion of benzoyl chlorides to the corresponding 2-imidazoles in good yields.

Keywords:

• Heteropolyacids
• imidazole
• recyclable catalysts
