We have reported the preparation of peptide nanofibers decorated with zirconium oxide nanoparticles for the first time as a novel, non-toxic, inexpensive and recyclable catalyst for the amination of aryl halides and synthesis of biaryl and symmetrical sulfides (via reaction of aryl halides with S8 or 2-thiobarbituric acid as sulfur transfer reagents). The structure of the catalyst was studied by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), atomic absorption spectroscopy (AAS), UV-visible absorption and fluorescence spectroscopy.

An application for dechalcogenization of aryl dichalcogenides via copper catalysis to synthesize aryl chalcogenides is disclosed. This approach is highlighted by the practical conditions, broad substrate scope, and good functional group tolerance with several sensitive groups such as aldehyde, ketone, ester, amide, cyanide, alkene, nitro, and methylsulfonyl. Furthermore, the robustness of this methodology is depicted by the late-stage modification of estrone and synthesis of vortioxetine. Remarkably, synthesis of more challenging organic materials with large ring tension under milder conditions and synthesis of some halogen contained diaryl sulfides which could not be synthesized using metal-catalyzed coupling reactions of aryl halogen are successfully accomplished with this protocol.

A highly chemoselective, efficient and nano-Pd catalyzed protocol for the rapid construction of sulfoxides and sulfones via the oxidation of symmetrical and unsymmetrical sulfides using H2O2 as an oxidant has been developed, respectively. The ready availability of starting materials, easy recovery and reutilization of the catalyst, wide substrate scope, and high yields make this protocol an attractive alternative. The process also involves the metal-free and microwave-promoted synthesis of symmetrical diarylsulfides, and FeCl3-mediated preparation of symmetrical diaryldisulfides through the reaction of arenediazonium tetrafluoroborates with Na2S·9H2O as a sulfur source. In addition, unsymmetrical sulfides were generated via the K2CO3-mediated reaction of arenediazonium tetrafluoroborates with symmetrical disulfides.

In this work, complex of Ni-modified graphene oxide was prepared and characterized using FT-IR spectroscopy, SEM, XRD, TGA and ICP-OES techniques. This compound used as an efficient and recoverable catalyst for the C–S coupling reaction using sulfur-transfer reagents (S8 or thiourea). The catalyst was easily separated using a simple filtration and reusable without significant loss of their catalytic efficiency.
