Octaflurodibenzothiophen is synthesized by Ullmann coupling of bis(o-bromotetrafluorophenyl) sulphide and is shown to udergo nucleophilic substitution in the 2-position by methoxide ion. Similarly, substitution in octafluorothianthren occurs in the 2-position. The orientation of substitution in octafluorodibenzothiophen was deduced from the NMR spectra of the products and of the biphenyls which are
八氟二苯并噻吩通过双(邻-溴四氟苯基)硫化物的乌尔曼偶合而合成,并显示在2-位被甲醇离子亲核取代。类似地,八氟噻吩中的取代发生在2位。由产物和联苯的NMR光谱推导八氟二苯并噻吩中的取代取向,所述产物和联苯是通过用阮内镍将二苯并噻吩脱硫而产生的。
