State Key Laboratory of Fine Chemicals, Dalian University of Technology, Dalian 116012, China

Received Date: 28 November 2008

A highly efficient benzylation of arenes and heteroarenes catalyzed by HfCl₄/HfO₂ has been developed. Broad scope of benzylation reagents have been used in this process with high yields under mild condition. Additionally, the HfO₂ can be re-used after the reaction.
