The present work demonstrates the C-S cross-coupling reaction between aryl halides and thiols using nickel nanoparticles (Ni NPs) supported on reduced graphene oxide (Ni/RGO) as a heterogeneous catalyst. It is observed that the uniformly dispersed Ni NPs supported on RGO could exhibit excellent catalytic activity in C-S cross-coupling reactions and the catalytic application is generalized with diverse coupling partners. Although the electron-rich planar RGO surface helps in stabilizing the agglomeration-free Ni NPs, the catalytic process is found to occur involving Ni(II) species and the recovered catalyst containing both Ni(0)/Ni(II) species is equally efficient in recycle runs. A correlation of loading of Ni species, size of NPs and the intermediate Ni-related heterostructures formed during the catalytic process has been established for the first time, and found to be best in the C-S cross-coupling reaction for Ni(0) and Ni(II) NPs of the average sizes 11-12 nm and 4 nm, respectively.

We report here an efficient and mild method for constructing C-S bonds. The reactions were carried out with Na2S2O3 as a sulfurating reagent, CuSO4 as a catalyst, and water as solvent without any surfactant. The products were achieved in moderate to excellent yields at room temperature under air. Notably, this reaction is compatible with various biomolecules including amino acids, oligosaccharides, nucleosides, proteins, and cell lysates. This journal is

A highly efficient Cu-catalyzed dual C-S bonds formation reaction, proceeding in alcohol and water under air, is reported, in which inodorous stable Na2S2O3 is used as a sulfurating reagent. This powerful strategy provides a practical and efficient approach to construct thioethers, using readily available aromatic amines and alkyl halides as starting materials. Sensitive and synthetic useful functional groups could be tolerated. Furthermore, pharmaceuticals, glucose, an amino acid, and a chiral ligand are successfully furnished by this late-stage sulfuration strategy.
