Synthesis of Diaryl Sulfides by Nickel(II)-Catalyzed Arylation of Arenethiolates

Efficient CuO‐Nanoparticle‐Catalyzed CS Cross‐Coupling of Thiols with Iodobenzene

“…[2] To overcome these difficulties, considerable attention has been focused on the development of catalytic systems for the C À S cross-coupling of thiols with aryl halides. [3][4][5][6][7] From an industrial standpoint, these reactions are attractive because the cost and environmental impact of the process (E factor) are relatively low.…”

“…[3] Palladium-, [4] nickel-, [5] copper-, [6] and cobalt-based [7] catalytic systems have since been studied for this purpose. Although useful methods are currently available, the requirement of high temperatures, high catalyst loadings, or specially designed phosphine ligands has prompted a search for new methods.…”

Well‐Defined Allylnickel Chloride/N‐Heterocyclic Carbene [(NHC)Ni(allyl)Cl] Complexes as Highly Active Precatalysts for CN and CS Cross‐Coupling Reactions

“…[16] Although nickel-catalyzed thiolation of aryl halides with thiols has been described, [17] usually high catalyst loadings were required. Very recently, Zhang and co-workers have reported the first (NHC)-based nickel(0) catalyst for C À S coupling reactions.…”

Transition metal- and solvent-free synthesis of unsymmetrical diaryl sulfides and selenides under ball-milling

“…6 Hence there has been an obvious interest towards the development of synthetic methodologies for the synthesis of these compounds. The majority of the reported protocols involved transition metals like Pd, [7][8] Cu, [9][10][11][12] Ni, [13][14][15] and Fe [16][17][18] in the reaction of aryl halides or aryl boronic acids to form chalcogenides. But few transition metal-free procedures were also reported for the reaction of aryl diazonium salts and lithium, sodium and potassium salt of arene thiolate / selenolate/ tellurolate.…”
