| Abstract: | A new approach for preparation of benzhydryl ethers with Fe2(SO4)3·xH2O as a clean catalyst is reported in this paper.With 1mol% Fe2(SO4)3·xH2O,benzhydrol could efficiently react with primary alcohols,secondary alcohol and benzyl alcohol with 77%-87% yields within 1.5-3 hours.After reaction,the catalyst Fe2(SO4)3·xH2O could be recovered by simply filtration,and water is the only by-product in this procedure.Clean catalyst and atom economy reaction make our method an alternative green procedure for preparation of benzhydryl ethers. |
