Several aromaticcompounds containing one or two C6F5S groups have been prepared by nucleophilic displacement reactions using CuSC6F5 in DMF solution. Aromatic iodine or bromine, rather than chlorine of fluorine is replaced by the SC6F5 group using CuSC6F5. A mechanism is postulated. New compounds prepared include -(C6F6F5S)2C6H4, - and -(C6F5S)2C6F4 and XC6H4SC6F5(X=C1, NO2, I, CH3, CO2C2H5).
通过在DMF溶液中使用CuSC 6 F 5进行亲核取代反应,已经制备了几种含有一个或两个C 6 F 5 S基团的芳族化合物。使用CuSC 6 F 5代替SC 6 F 5基团取代芳族的碘或溴,而不是氟的氯。假定一种机制。制备的新化合物包括-(C 6 F 6 F 5 S)2 C 6 H 4,-和-(C 6 F 5 S)2 C 6F 4和XC 6 H 4 SC 6 F 5(X = C1,NO 2,I,CH 3,CO 2 C 2 H 5)。
C−S Cross‐Coupling of Aryldiazonium Salts with Thiols Mediated by Gold
A gold mediated C−S cross-coupling of aryldiazonium salts with thiols is described. The relevance of the protocol is the use of the readily available and simple gold complex Me2SAuCl. The reaction proceeds under soft conditions and has a broad scope in both the diazonium salt and the thiol.
描述了金介导的芳基重氮盐与硫醇的 C−S 交叉偶联。该协议的相关性是使用容易获得且简单的金络合物 Me 2 SAuCl。该反应在温和的条件下进行,并且在重氮盐和硫醇中都有较宽的范围。
