Facile and selective syntheses of various diaryl sulfides from aryl halides and aromatic thiols by the aid of an in situ generated nickel(0) catalyst are reported. The nickel(0) induces a C–S cleavage, as well.

The cross-coupling reaction of arylchlorides with aliphatic and aromatic thiols catalyzed by palladium complexes of the strongly binding bisphosphine CyPF-tBu ligand (1) is reported. Most of the reactions catalyzed by complexes of ligand 1 occur with turnover numbers that exceed those of previous catalysts by two orders of magnitude. The reactions occur with excellent yields, broad scope and high

A Chan–Lam-type C–S coupling reaction using sodium aryl sulfinates has been developed to provide diaryl thioethers in up to 92% yields in the presence of a copper catalyst and potassium sulfite. Both electron-rich and electron-poor sodium aryl sulfinates and diverse organoboron compounds were tolerated for the synthesis of aryl and heteroaryl thioethers and dithioethers. The mechanistic study suggested

to a THT! Screening a diverse library of thioether ligands led to the discovery of tetrahydrothiophene (THT) as a highly reactive and selective ligand for Pd‐catalyzed allylicCHoxidation reactions (see scheme). This novel ligand system provides some of the highest reported yields for the formation of (E)‐linear allylic acetates through allylicCH activation chemistry (BQ = 1,4‐benzoquinone).
