Yi, Jun,Fu, Yao,Xiao, Bin,Cui, Wei-Chen,Guo, Qing-Xiang
, p. 205 - 208 (2011)
A Pd-catalyzed coupling reaction of ArBr/ArCl/ArOTf with sodium thiosulfate takes place in presence of Cs2CO3 at 80 °C. The reaction mixture is directly treated with Zn/HCl to afford aryl thiols in good to excellent yields.

Non-aqueous reduction of aromatic sulfonyl chlorides to thiols using a dichlorodimethylsilane-zinc-dimethylacetamide system
Uchiro, Hiromi,Kobayashi, Susumu
, p. 3179 - 3182 (1999)
A new and efficient method for the non-aqueous reduction of sulfonyl chlorides to affored the corresponding thiols by use of a dichlorodimethylsilane-zinc-dimethylacetamide system was successfully developed. Various aromatic thiols were prepared in high yield by easy operation. Continuous reactions with the above reduction using the prepared thiol were also demonstrated.

Copper-Catalyzed Direct Synthesis of Aryl Thiols from Aryl Iodides Using Sodium Sulfide Aided by Catalytic 1,2-Ethanedithiol
Xue, Hongyu,Jing, Bing,Liu, Shasha,Chae, Junghyun,Liu, Yajun
, p. 2272 - 2276 (2017)
A copper-catalyzed direct and effective synthesis of aryl thiols from aryl iodides using readily available Na 2 S·9H 2 O and 1,2-ethanedithiol was described. A variety of aryl thiols were readily obtained in yields of 76-99%. In this protocol, Na 2 S·9H 2 O was used as ultimate sulfur source, and 1,2-ethanedithiol functioned as an indispensable catalytic reagent.

Fujimori, Ken,Togo, Hideo,Oae, Shigeru
, p. 4921 - 4924 (1980)
Arenesulfonic acids, its sodium salts, and alkyl arenesulfonates were reduced readily to the corresponding arenethiols quantitatively with triphenylphosphine in the presence of iodine.
Catalytic transfer hydrogenation of aryl sulfo compounds
Chen, Xinzhi,Zhou, Shaodong,Qian, Chao
, p. 179 - 185 (2012)
A new method to reduce aryl sulfo compounds via transfer hydrogenation was investigated, using Pd/C as a catalyst, and 2-propanol or formic acid as hydrogen sources. This new process is simple and clean.
Thermal reactions of chloroarenes with hydrogen sulfide in the presence of methanol
Deryagina,Sukhomasova,Levanova,Papernaya,Korchevin
, p. 1624 - 1630 (2005)
Gas-phase reactions of chloroarenes (ClC6H4X, X = H, 4-CH3, 4-OH, 4-Cl, 4-CF3) with hydrogen sulfide or its precursors were investigated in the presence of methanol, which was a stronger H-donor than hydrogen sulfide. Introducing methanol increased the selectivity of arenethiols formation at X = H and 4-CH3 and did not affect the reaction selectivity at acceptor X. The efficiency of methanol influence was considered from the viewpoint of free-radical reaction mechanism and the stability of the arenethiyl radicals. 2005 Pleiades Publishing, Inc.
Metal–organic framework MOF-199-catalyzed direct and one-pot synthesis of thiols, sulfides and disulfides from aryl halides in wet polyethylene glycols (PEG 400)
Soleiman-Beigi, Mohammad,Sadeghizadeh, Fatemeh,Basereh, Ali
, p. 572 - 583 (2017)
A highly porous metal–organic frame work Cu3 BTC2 (copper(II)-benzene-1,3,5-tricarboxylate) that is known as MOF-199 was synthesized from the reaction of 1,3,5-benzenetricarboxylic acid and Cu(OAc)2·H2O by a solvothermal method and characterized by several techniques including FT-IR, XRD, EDX and scanning electron microscopy. The MOF-199 used as an efficient catalyst for one-pot synthesis of thiols by domino reactions of aryl halides and thiourea, and subsequently conversion to aryl alkyl sulfides and diaryl disulfides in polyethylene glycols (PEGs). A variety of aryl alkyl sulfides can be obtained in good to excellent yields in a relatively short reaction time and in the presence of the trace amount of catalyst. Also, the catalyst can be separated from the reaction mixture by decanting, and be reused without significant degradation in catalytic activity.
