6-pentafluorobiphenyl which undergoes an intramolecular nucleophilic substitution reaction with potassium carbonate in dimethyl formamide. 1,2,3,4-Tetrafluorodibenzofuran undergoes nucleophilic substitution reactions with sodium hydrogen sulphide, sodium thiomethoxide and LAH involving replacement of the 3-fluorine atom; this was established by reference to an Ullmann reaction between o-bromo-anisole and bromo-2,3,5
1,2,3,4-四氟二苯并呋喃是由六氟苯和邻-硫代苯甲醚经2'-羟基-2,3,4,5,6-五氟联苯制备的,该化合物与碳酸钾在二甲基甲酰胺中进行分子内亲核取代反应。1,2,3,4-四氟二苯并呋喃与硫化氢钠,硫代甲醇钠和LAH进行亲核取代反应,涉及到3-氟原子的取代;这是通过参考邻溴代茴香醚与溴代2,3,5,6-四氟苯之间的乌尔曼反应建立的。
