, p. 2306 - 2309 (2010)
The photoinduced substitution of the 2-naphthoxide anion was carried out using diethylphosphite, benzenethiolate or 2-naphthalenethiolate anions in the presence of an electron acceptor. The corresponding products were afforded in good yield. This is a sim

A series of 1-(arylthio)naphthalen-2-ols have been synthesized by condensation of naphthalen-2-ol with 1,2-diaryldisulfanes in the presence of iodine under microwave irradiation and conventional heating methods. Structures of the products were elucidated

A highly efficient strategy for the direct thiolation of phenols under transition metal-free and solvent-free conditions has been developed. These reactions are operationally simple with employing air (molecular oxygen) as an ideal oxidant and can selectively provide mono- and dithiolation products in good to excellent yields under basic conditions. The reaction tolerates a broad range of aryl thiols and arenes and is especially applicable for large-scale synthesis.

An efficient TBAI (tetrabutylammonium iodide)-mediated C–H sulfenylation of arenes with arylsulfonyl hydrazides in dipropylene glycol dimethyl ether (DPDME) was described. Various electron-rich arenes were applicable in the reaction, such as naphthylamine, naphthol, aniline, indole, pyrrole, and imidaz o [1,2-a] pyridine. A wide range of the aryl sulfides were obtained with good functional group tolerance. This method features green reaction conditions (odorless and easily available sulfur reagent, recyclable TBAI, and DPDME as solvent), and broad substrate scope. The synthetic potential is demonstrated by gram-scale synthesis and downstream transformations. The mechanism studies show that the reaction is achieved through electrophilic substitution process, and diaryl disulfide may be the main intermediate.

, p. 7331 - 7340 (2018/07/29)
Organosulfides have great significance and value in synthetic and biological chemistry. To establish a versatile and green methodology for C-S bond generation, we successfully developed a new aerobic cross-dehydrogenative coupling of C-H and S-H to synthe
Photoinitiated Synthesis of Sulfides in Water
Rodriguez, Sergio A.,Mena, Leandro D.,Baumgartner, Maria T.
, p. 919 - 924 (2016/08/10)
Herein, we report a synthetic route to obtain aryl sulfides using inexpensive and non-toxic reactants and water as solvent, that avoids the use of catalysts or heating. The photoinduced reaction between soluble substrates and a series of thiols in alkaline aqueous medium produces the corresponding sulfides in moderate to good yields.

A novel, efficient and unprecedented green protocol for the formation of C-S bonds has been developed under metal-free conditions. This protocol involves the synthesis of aryl sulfides through the cross-dehydrogenative coupling of readily available aryl t
Sulfenylation of nitroalkanes and hydroxyaryls
Blanco, Guillermo A.,Baumgartner, Maria T.
supporting information; experimental part, p. 7061 - 7063 (2012/01/05)
The sulfenylation of nitroalkanes and hydroxyaryls in DMSO using aryl disulfides as sulfenylating reagents was studied. The corresponding arylthionitroalkanes and arylthiohydroxyaryls were obtained in moderate to good yields in very mild conditions, thus improving the reported procedures for the synthesis of these compounds.
