, p. 6646 - 6653 (2016/09/28)
A mild method for the Cu0-catalyzed chemoselective C[sbnd]S cross-coupling of 2-mercaptoimidazole derivatives with a series of with differently substituted iodobenzenes and iodothiophenes at 100 °C is described. This method proceeds efficiently without ligands and at low catalyst loading (3 mol %), without the need for stringent inert conditions. Under optimized conditions, the S-arylated products were obtained in good yields of up to 90%.

Diaryl and heteroaryl sulfides: Synthesis via sulfenyl chlorides and evaluation as selective anti-breast-cancer agents

A mild protocol for the synthesis of diaryl and heteroaryl sulfides is described. In a one-pot procedure, thiols are converted to sulfenyl chlorides and reacted with arylzinc reagents. This method tolerates functional groups including aryl fluorides and chlorides, ketones, as well as N-heterocycles including pyrimidines, imidazoles, tetrazoles, and oxadiazoles. Two compounds synthesized by this method exhibited selective activity against the MCF-7 breast cancer cell line in the micromolar range.

Cu(ii)-catalyzed direct thiolation of azoles with thiols is described via intermolecular C-S bond formation/C-H functionalization under oxidative conditions. Both aryl thiols and aliphatic thiols are used as coupling partners, and furnished the thiolation
An efficient copper-catalyzed cross-coupling reaction of thiols with aryl iodides
Kao, Hsin-Lun,Chen, Chin-Keng,Wang, Yu-Jen,Lee, Chin-Fa
experimental part, p. 1776 - 1781 (2011/05/03)
Commercially available Cu2O powder is a very reactive catalyst for the coupling of thiols to aryl iodides. A variety of functional groups including esters, unprotected amines, alcohols, and heterocycles tolerate the reaction conditions. Moreover, di-ortho-substituted aryl iodides with sterically demanding substrates were also coupled to give the desired aryl thioethers in good to excellent yields. Copyright

A novel series of imidazole containing histamine H3 receptor ligands were investigated and found to be potent functional antagonists. After improving the stability of these molecules towards liver microsomes, these compounds were found to have
Iron-catalyzed S-arylation of thiols with aryl iodides
Correa, Arkaitz,Carril, Monica,Bolm, Carsten
, p. 2880 - 2883 (2008/12/23)
(Chemical Equation Presented) Strike while the iron is hot: An efficient iron-catalyzed protocol for the S-arylation of aromatic and heteroaromatic thiol derivatives has been developed, which involves an inexpensive catalyst system formed by combining FeCl3 and N,N′-dimethylethylenediamine at 135°C. This method avoids the use of expensive and/or air-sensitive ligands and provides in most cases the desired sulfide in high yields.
