This work describes a nickel-catalyzed Ullmann-type thiolation of aryl iodidesunder mild electrochemical conditions. The simple undivided cell with graphene/nickel foam electrode setups offers excellent substrate tolerance, affording aryl and alkyl sulfides in good chemical yields. Furthermore, the mechanism for this electrochemical cross-coupling reaction has been investigated by cyclic voltammetry

The synthesis of a series of molecular chains by use of C–S, C–N and C-Alkyne cross coupling, as well as bromo by iodo exchangereactions, has been reported. Two different types of chains R–C6H4–S–C6H4–CC–C6H4–NH–C6H4–Br, and R–C6H4–S–C6H4–NH–C6H4–CC–C6H4–Br (R=MeO, CN, NO2) could be obtained starting from the same thioether but applying different reaction sequences. Compounds R–C6H4–CC–C6H4–S–C6H4–NH–C6H4–Br
据报道,通过使用C–S,C–N和C-炔烃交叉偶联以及溴的碘交换反应,可以合成一系列分子链。两种不同类型的链R–C 6 H 4 –S–C 6 H 4 –C C–C 6 H 4 –NH–C 6 H 4 –Br和R–C 6 H 4 –S–C 6 H 4 –NH–C 6 H 4 –C C–C 6 H 4 –Br(R = MeO,CN,NO 2可以从相同的硫醚开始,但应用不同的反应顺序获得。化合物R–C 6 H 4 –C C–C 6 H 4 –S–C 6 H 4 –NH–C 6 H 4 –Br是由二芳基乙炔经碘代取代后与C–S和a交替生成的,由二芳基乙炔制得。 C–N交叉耦合。
A template free protocol for fabrication of a Ni(<scp>ii</scp>)-loaded magnetically separable nanoreactor scaffold for confined synthesis of unsymmetrical diaryl sulfides in water
An environmentally benign nickel(ii)-based magnetic nanoreactor has been developed for oxidative coupling of arenethiols with arylhydrazines to form unsymmetrical diaryl sulfides in water at room temperature.

The sugar alcohol meglumine can solubilize organic compounds in water to synthetically useful levels, allowing the formation of enforced electron donor acceptor (EDA) complexes in water. These EDA complexes offer a new activation for light driven C−C and C−S cross-coupling chemistry without sensitizers.
