Benzylation of arenes and heteroarenes catalyzed by HfCl4/HfO2

摘要

A highly efficient benzylation of arenes and heteroarenes catalyzed by HfCl_4/HfO_2 has been developed.Broad scope of benzylation reagents have been used in this process with high yields under mild condition.Additionally,the HfO_2 can be re-used after the reaction.
