The organic superbase t-Bu-P4-catalyzed direct thiolation of trimethyl(perfluorophenyl)silanes and thiosulfonates was developed. Yields of perfluorophenylsulfides of up to 97% under catalysis of 5 mol% t-Bu-P4 were achieved. This method was shown to provide an efficient way to construct the perfluorophenyl–sulfur bond under mild metal-free reaction conditions.

synthesized from pentafluorobenzene and arylthiols or diaryldisulfides in the presence of copper catalyst and ligand by using O2 as the oxidant, t-BuOLi as the base at 100 °C. The ligand (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-one (L) played an indispensable role in the reaction. This work contains a notable mode of CF bondactivation, which is in the ortho position to the CH bond of pentafluorobenzene
Copper-catalyzeddecarboxylative thiolation using molecular oxygen as the sole oxidant was developed. A variety of aromaticcarboxylicacids including 2-nitrobenzoic acids, pentafluorobenzoic acid and several heteroaromatic carboxylicacids undergo efficient...
C–H sulfidation or selenation of arenes by a Pd(II)/Cu(II) catalytic system: Preparation of unsymmetrical sulfides or selenides by C–H functionalization has been disclosed. This protocol could be applied a various of arenes. In the case of using an indolizine and pentafluorobenzene, bis‐sulfidated product were obtained.

The reactions of various fluoroaromatics, C6F6−xHx, and C6F5X (X = C6F6, Cl, Me, NO2, CF3, COCl, CH2Br, OMe, and NH2) with lead(II) benzenethiolate in DMF have been examined. Lead thiolate acted as an excellent source of benzenethiolate anions and displacement of fluorine, chlorine or the nitro group was observed. The new products have been characterized by elemental analysis, and NMR (H−1 and F−19)
各种氟代芳烃,C 6 F 6-x H x和C 6 F 5 X(X = C 6 F 6,Cl,Me,NO 2,CF 3,COCl,CH 2 Br,OMe和NH 2的反应)中已检测了DMF中的苯硫醇铅(II)。硫醇铅是苯硫醇根阴离子的极好来源,并观察到了氟,氯或硝基的置换。这些新产品已通过元素分析,NMR(H-1和F-19),红外和质谱进行了表征。
