An efficient synthetic method of N-arylphenothiazines from o-sulfanylanilines under transition-metal-free conditions is disclosed. An N- and S-arylation sequence of o-sulfanylanilines enabled us to synthesize a wide variety of N-arylphenothiazines. In par
Modified conditions for copper-catalyzed ipso-thiolation of arylboronic acid esters with thiosulfonates

supporting information, p. 85 - 88 (2018/01/26)
An efficient ipso-thiolation of arylboronic acid esters with thiosulfonates has been achieved under mild and odorless conditions using a copper catalyst. The use of TMEDA and cesium fluoride as the ligand and base, respectively, dramatically facilitated the desired transformation. The method exhibited a broad substrate scope, which allowed for the expeditious synthesis of diverse aryl sulfides from easily available starting materials.

An efficient deborylthiolation of aryl- and alkenylborons with thiosulfonates has been achieved under mild conditions using a copper catalyst. All steps of the experimental process were free from unpleasant odors. The mild reaction conditions as well as ready availability of boron compounds and thiosulfonates enabled easy access to an array of sulfides, including those bearing sensitive functional groups.
8-hydroxyquinolin-N-oxide-promoted copper-catalyzed C-S cross-coupling of thiols with aryl iodides

8-Hydroxyquinolin-N-oxide was identified as a superior ligand for CuI-catalyzed C-S coupling reactions of aryl iodides with thiols to afford the corresponding thioethers in excellent yield. The method shows excellent chemoselectivity and high functional-group tolerance in both coupling partners. Copyright
Preparation of optically active ortho-chloro- and ortho-bromophenyl sulfoxides
Imboden, Christoph,Renaud, Philippe
, p. 1051 - 1060 (2007/10/03)
The preparation of the diastereomerically pure menthyl (S)-2-chloro- and (S)-2-bromophenyl sulfinates by esterification of the corresponding sulfinic acids with (1R,2S,5R)-(-)-menthol and recrystallization/epimerization is reported. The two sulfinates have been converted into enantiomerically pure aryl, vinyl and alkyl sulfoxides by reaction with organomagnesium reagents. These sulfoxides are useful chiral auxiliaries to control the stereochemical outcome of radical reactions.
Synthesis and Crystal Structure of a New C2-Symmetric Chiral Bis-sulfoxide Ligand and Its Palladium(II) Complex
Tokunoh, Ryosuke,Sodeoka, Mikiko,Aoe, Kei-ichi,Shibasaki, Masakatsu
, p. 8035 - 8038 (2007/10/02)
A new chiral bis-sulfoxide ligand (S,S)-1,2-bis(p-tolylsulfinyl)benzene (BTSB), which possesses S,S-bidentate chelating donor atoms on an aromatic ring, was synthesized.Pd, Rh, and Ru readily gave adducts with this ligand.The crystal structure of PdCl2bt
