Abstract
4-(4'-cyano-2'-fluorophenoxy) phenol is an important intermediate of phenoxypropionate herbicide. The new synthesis technique of 4-(4’-cyano-2’-fluorophenoxy) phenol is reviewed. 4-hydroxyanisole and 3, 4-difluorobenzonitrile is used as the major starting materials to obtain 4-(4'-cyano-2'-fluorophenoxy) anisole. Then 4-(4'-cyano-2'-fluorophenoxy) phenol is obtained by deoxidizing 4-(4'-cyano-2'fluorophenoxy) anisole with BBr3. Its chemical structure is characterized by IR, 1H-NMR and mass spectrum. The total yield is 64% and the purity is 95.2%. Thereby this method overcomes the disadvantages of small amount of production and low yield.
