Document Type : Research Note


Malekan Branch, Islamic Azad University, Malekan, I.R. IRAN


In this research work, The methoxy- m-Terphenyls are demethylated with boron tribromide  solution  in dichloromethane.The  methoxy - m -Terphenyls required , are prepared from the reaction of methoxy- aryl- grignards with 2, 6- dichloroiodobenzene in refluxing THF. The hydroxy- m- Terphenyls  can be  used for the preparing polyesters , polyethers , cyclophanes , benzoquinones  and  other derivatives of Terphenyls.
