We report a general copper-catalyzed cross-coupling of thiols with aryl halides by using N-aryl- N′-alkyl oxalic diamide ( L3) or N, N′-dialkyl oxalic diamide ( L5) as the ligand. Both aryl and alkyl thiols can be coupled with unactivated aryl bromides and chlorides to give the desired products in good yields. Furthermore, this system features a broad substrate scope and good tolerance of functional groups. Importantly, the oxalic diamides are stable and can be prepared easily from commercially available and cheap starting materials. [ABSTRACT FROM AUTHOR]

A transition-metal-free, two-fold CS bond cross-coupling reaction of dihalopyridines with different thiols is described, which provides the resulting dithioethers in good to excellent yields. [ABSTRACT FROM AUTHOR]

Commercially available CuO powder is found to be a suitable catalyst for C-S coupling reaction between aryl- and alkyl thiols and aryl iodides. Functional groups including halides, ketone, unprotected amine and heterocycles were tolerated by the reaction conditions employed. [ABSTRACT FROM AUTHOR]

Novel CuO on mesoporous silica is prepared under a convenient approach, and has been shown to be an efficient catalyst for cross-coupling reactions of thiols with aryl iodides with only 1.0–5.0 mol% catalyst loading. [ABSTRACT FROM AUTHOR]

FeCl3in combination with bisphosphine ligands represents an efficient catalyst system for the cross-coupling of aryl- and alkyl thiols with aryl iodides, a broad spectrum of functional groups can be tolerated during the catalysis. [ABSTRACT FROM AUTHOR]

We describe the synthesis of thioesters via copper‐ or iron‐catalyzed coupling of thiols with aldehydes on application of microwave irradiation. In this protocol, a variety of aliphatic and aromatic aldehydes and thiols were used, and the products were obtained in good to excellent yields. [ABSTRACT FROM AUTHOR]

A practical synthetic method for the synthesis of diversified thioethers using oxalic diamides as highly air ‐ stable ligands through copper catalysis is demonstrated. A variety of aryl and alkyl thiols were successfully coupled with aryl bromides and aryl chlorides to afford the corresponding thioethers in good yields. This work is the first copper ‐ catalyzed thioetherification of unactivated aryl chlorides. More information can be found in the Full Paper by C. ‐ F. Lee et al. on page 10087.

Abstract: The general procedure for the rhodium-catalyzed cross-coupling of thiols with aryl iodides is described. The catalytic system consists of 5mol% of [RhCl(cod)]2 and 10mol% of PPh3 as a ligand. A variety of aryl iodides reacted with thiols, giving aryl thioethers in good to excellent yields. It is important to note that the deactivated aryl iodides such as 4-iodoanisole is worked smoothly to provide the corresponding aryl thioethers in excellent yields. Functional groups such as free-amines, chloro, are all tolerated under the employed reaction conditions. [Copyright &y& Elsevier]
