Nucleophilic 1,2-aminothiol compounds readily reduce typically-insoluble elemental sulfur to polysulfides in both water and nonpolar organic solvents. The resulting anionic polysulfide species are stabilized through hydrogen-bonding interactions with the proximal amine moieties. These interactions can facilitate sulfur transfer to alkenes.

Paragraph 0032-0034, (2018/04/03)
The invention provides 1-aryl ethanesulfonic acid and a preparation method of its derivative. The preparation method comprises the following steps that (a) 1-aryl halogensated ethane represented in aformula (I) and sodium hydrosulfide react to generate 1-

In this paper we report an efficient and mild procedure for the conversion of organic thiocyanates to thiols in the presence of phosphorus pentasulfide (P2S5) in refluxing toluene. The method avoids the use of expensive and hazardous transition metals and harsh reducing agents, as required by reported methods, and provides an attractive alternative to the existing methods for the conversion of organic thiocyanates to thiols.
Ligand dependence of the synthetic approach and chiroptical properties of a magic cluster protected with a bicyclic chiral thiolate

supporting information; experimental part, p. 4630 - 4632 (2012/06/15)
Chiral gold clusters stabilised by enantiopure thiolates were prepared, size-selected and characterised by circular dichroism and mass spectrometry. The product distribution is found to be ligand dependent. Au25 clusters protected with camphorthiol show clear resemblance of their chiroptical properties with their glutathionate analogue.

Dutch Resolution: Separation of enantiomers with families of resolving agents. A status report
Kellogg, Richard M.,Nieuwenhuijzen, Jose W.,Pouwer,Vries, Ton R.,Broxterman, Quirinus B.,Grimbergen, Reinier F.P.,Kaptein, Bernard,La Crois, Rene M.,De Wever, Ellen,Zwaagstra, Karen,Van Der Laan, Alexander C.
, p. 1626 - 1638 (2007/10/03)
Dutch Resolution is the term given to the use of mixtures (families) of resolving agents in classical resolutions. In this status report an overview is given of the latest results and new (possible) families of resolving agents are introduced. The concept of families is discussed as well as the factors that come into play on use of families. Practical aspects of Dutch Resolution in particular and resolutions in general are discussed.

Highly enantioselective reaction of α-lithio 2-quinolyl sulfide using chiral bis(oxazoline)s: A new synthesis of enantioenriched thiols
Nakamura, Shuichi,Furutani, Akinori,Toru, Takeshi
, p. 1690 - 1695 (2007/10/03)
The enantioselective reaction of α-lithio benzyl 2-quinolyl sulfide proceeds through a dynamic thermodynamic resolution pathway, giving the products with high stereoselectivity. The products afford chiral thiols without racemization upon removal of the quinolyl group. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
The configurational stability of an enantioenriched α-thiobenzyllithium derivative and the stereochemical course of its electrophilic substitution reactions; synthesis of enantiomerically pure, tertiary benzylic thiols
Stratmann, Oliver,Kaiser, Bernd,Frohlich, Roland,Meyer, Oliver,Hoppe, Dieter
, p. 423 - 435 (2007/10/03)
The lithium compound (S)-7, formed by deprotonation of the (S)-S-1-phenylethyl thiocarbamate (S)-10, is configurationally stable at -70°C. Even at elevated temperatures it racemizes only very slowly. It represents the first essentially enantiopure αthioca
A general and mild synthesis of thioesters and thiols from halides
Zheng, Tu-Cai,Burkart, Maureen,Richardson, David E.
, p. 603 - 606 (2007/10/03)
The conversion of a wide variety of halides to thioesters by reaction with potassium thiocetate under mild conditions is described, and the generality of the method is demonstrated.
