Catenation of 2,2'-Bis(ethylthiomethyl)biphenyl with Copper(I) Bromide
Toyota, Shinji,Matsuda, Yohei,Oki, Michinori,Akashi, Haruo
, p. 31 - 32 (1995)
Treatment of 2-(ethylthiomethyl)phenyllithium with copper(I) bromide afforded a polymeric coordination compound in which 2,2'-bis(ethylthiomethyl)biphenyl molecules were linked by copper(I) bromide cores.This polymeric complex dissociates on dissolution in organic solvents and reforms on recrystalization from the solution.Other copper(I) salts also gave similar compounds, when reacted with the lithium compound.
Chemoenzymatic Deracemization of Chiral Sulfoxides
Nosek, Vladimír,Mí?ek, Ji?í
supporting information, p. 9849 - 9852 (2018/07/31)
The highly enantioselective enzyme methionine sulfoxide reductase A was combined with an oxaziridine-type oxidant in a biphasic setup for the deracemization of chiral sulfoxides. Remarkably, high ee values were observed with a wide range of substrates, thus providing a practical route for the synthesis of enantiomerically pure sulfoxides.
Palladium- and Nickel-Catalyzed Decarbonylative C-S Coupling to Convert Thioesters to Thioethers
Ichiishi, Naoko,Malapit, Christian A.,Wo?niak, Aukasz,Sanford, Melanie S.
supporting information, p. 44 - 47 (2018/01/17)
This Letter describes the development of a catalytic decarbonylative C-S coupling reaction that transforms thioesters into thioethers. Both Pd- and Ni-based catalysts are developed and applied to the construction of diaryl, aryl alkyl, and heterocycle-containing thioethers.
Sulfoxide-to-sulfilimine conversions: Use of modified Burgess-type reagents

Sulfoxides can directly be converted into N-cyanosulfilimines using a new Burgess-type reagent. By applying this strategy with a related reagent variant, synthetically valuable NH-sulfoximines have been prepared from sulfoxides via N-protected sulfilimines. The practical three-step reaction sequence is generally high yielding and applicable to a wide range of substrates. The sulfoxide-to-sulfilimine conversion can also be performed under solvent-reduced conditions in a ball mill. Copyright
Iodine-mediated thioetherification of alcohols with disulfides or NaSh under microwave irradiation
Hu, Bolun,Sun, Leilei,Tang, Riyuan,Hu, Huanan
, p. 2556 - 2562,7 (2020/09/16)
An efficient and novel method for the thioetherification of an alcohol with disulfides or NaSH under microwave irradiation is presented. In the presence of iodine, a variety of alcohols were smoothly S-alkylated with disulfides or NaSH to give the corresponding thioethers in moderate to excellent yields. Copyright
Triflic acid catalyzed reductive coupling reactions of carbonyl compounds with O-, S-, and N-nucleophiles
Gellert, Beate A.,Kahlcke, Nils,Feurer, Markus,Roth, Stefanie
supporting information; experimental part, p. 12203 - 12209 (2011/11/07)
Highly efficient metal-free reductive coupling reactions of aldehydes and ketones with a range of nucleophiles in the presence of triflic acid (1-5 mol %) as the catalyst are presented. The reactions can be performed at ambient temperature without exclusion of moisture or air. A range of symmetrical and unsymmetrical ethers were obtained by this method in high yields and short reaction times. For the first time, the influence of additional functionalization has been studied. Furthermore, the formation of thioethers from ketones (by addition of unmodified thiols) and of sulfonamides from either aldehydes or ketones has been achieved under catalytic conditions.
Zn in ionic liquid: An efficient reaction media for the synthesis of diorganyl chalcogenides and chalcogenoesters
Narayanaperumal, Senthil,Alberto, Eduardo E.,Gul, Kashif,Kawasoko, Cristiane Yuriko,Dornelles, Luciano,Rodrigues, Oscar E.D.,Braga, Antonio Luiz
experimental part, p. 4723 - 4730 (2011/06/27)
A straightforward and efficient methodology is described to synthesize structurally diverse diorganyl selenides, sulfides, seleno- and thioesters by using commercially available Zn dust in ionic liquid. Excellent yields were achieved under neutral conditions at room temperature in a short time. The solvent/ionic liquid is reusable and exhibited higher performance as compared with organic solvents.
Synthesis and reactions of novel triply thiolate-bridged diiron complexes [Cp*Fe(μ2-SR)3FeCp*] (Cp* = η5-C5Me5; R = Et, Ph)
Chen, Yanhui,Zhou, Yuhan,Qu, Jingping
, p. 666 - 671 (2009/01/30)
The novel thiolate-bridged diiron complexes [Cp*Fe(μ2- SR)3FeCp*] (1, R = Et; 2, R = Ph) have been obtained by the reaction of [Cp*FeCl]2 with LiSEt or LiSPh in THF. Treatment of 1 with CO or CNtBu in THF gives

Dithioacetals were reduced by 1,4-cyclohexadiene in the presence of a catalytic amount of Lewis acid to afford the corresponding sulfides in good yields.
