By using alkanes and mercaptans as the nucleophiles with di-tert-butyl peroxide (DTBP) as the oxidant, I2-catalyzed oxidative C(sp(3))-H/S-H coupling was achieved. This protocol provides a novel process to construct C(sp(3))-S bonds from commercially available hydrocarbons and mercaptans.
Eco-compatible three component strategies for C-S bond formation in thioether and S-aryl-carbamodithioate compounds catalyzed by copper(II) nanoparticles supported on modified AlPO<sub>4</sub>
One‐pot and three components C‐S bondformation reactions in thioethers and S‐aryl‐carbamodithioates have been catalyzed by a copper heterogeneous nano‐catalyst supported on modified AlPO4 under different reaction conditions. The above‐mentioned nano‐catalyst has been characterized by various techniques such as SEM, TEM, AFM, XRD, FT‐IR, UV–Vis, CV, BET, TGA, ICP and XPS spectrometry and its particle

An odorless and efficient protocol for the synthesis of benzyl phenyl sulfides is reported. Starting from environmentally friendly phenyl dithiocarbamates and commercially available benzyl halides as starting materials, the target compounds (benzyl phenyl sulfides) could be obtained smoothly and easily by using copper salt as catalyst and Cs2CO3 as base. This method features ligand/additive-free, the

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.
