Arylglyoxals: A novel and efficient reagent for the oxidation of thiols to homodisulfides

The stoichiometric oxidation of thiols to their corresponding homodisulfides by arylglyoxals has been described. The process has several advantages: high yields, short reaction times, simple experimental and work-up procedures. Figure Presented.

Dicationic Thiolate-Bridged Diruthenium Complexes for Catalytic Oxidation of Molecular Dihydrogen

Dicationic thiolate-bridged diruthenium complexes bearing sterically bulky alkane substituents on the thiolate ligands such as [Cp?Ru(μ-SiPr)2Ru(OH2)Cp?](OTf)2 have been found to work as effective catalysts toward oxidation of molecular dihydrogen into protons and electrons in protic solvents such as water and methanol. DFT calculations indicate that the sterically bulky alkane substituent in the complex plays an important role in facilitating the reaction step of the coordination of molecular dihydrogen.

Method for preparing disulfide bond containing compound by using TEMPO catalyst through aerobic oxidation

The invention discloses a method for preparing a disulfide bond containing compound by using a TEMPO catalyst through aerobic oxidation. The method comprises the following steps: adding R-SH, R'-SH and TEMPO into a solvent, and performing heating reflux in an aerobic environment, thereby preparing R-S-S-R'. The method achieves oxidative coupling reaction of thiophenol and mercaptan in the absence of transition metal and is high in yield, good in selectivity and free of over-oxidized product; for aliphatic mercaptan which is relatively poor in activity, the problem of oxidation can be solved by adding copper salt as a promoter, the yield is relatively high, and the reaction is greatly affected by a substitute group; the catalyst is easy to obtain, the reaction condition is gentle, and the method is applicable to large-scale production.

Ultrasound-Accelerated Synthesis of Asymmetrical Thiosulfonate S-Esters by Base-Promoted Reaction of Sulfonyl Chlorides with Thiols

Amberlyst A-26, Mg-Al hydrotalcite, potassium fluoride absorbed on alumina, triethylamine and pyridine have been tested as base catalysts and reagents for the reaction of sulfonyl chlorides with thiols to prepare thiosulfonate S-esters. The reactions were performed under solvent-free conditions or with a minimum amount of solvent assisted by magnetic stirring, ultrasound irradiation and microwave irradiation. Ultrasound irradiation has good effects on the synthesis of sterically hindered thiosulfonate S-esters in solvent-free media as well as in a minimum amount of anhydrous diethyl ether.

Methyl sulfinates as electrophiles in friedel-crafts reactions. Synthesis of aryl sulfoxides

The Friedel-Crafts reaction of methyl alkyl- and arylsulfinates with aromatic systems, activated by one or more electron-donating substituents (OH, OMe, NHR, NR2), provides alkyl aryl and diaryl sulfoxides under mild conditions and in moderate to good yields. The very high regioselectivity usually observed in these sulfinylation reactions is rationalized on the basis of a Wheland intermediate having a trigonal bypyramidal structure in which steric and electronic interactions are significant factors strongly destabilizing the attack to the ortho positions.

Rapid and efficient synthesis of symmetrical alkyl disulfides under phase transfer conditions

A one-pot, rapid and general method for the synthesis of symmetrical disulfides based on reaction of sulfur with sodium sulfide in the presence of didecyldimethylammonium bromide (DDAB) as a phase transfer catalyst is reported. Reaction with a variety of alkyl halides, at room temperature, afforded the disulfides in good to excellent isolated yields in a short time.

The invention concerns a method for preparing aromatic diphenyl thioethers. More particularly the invention concerns the preparation of 4-chloro-4′-thiomethyldiphenylether. The inventive method for preparing an aromatic diphenyl thioether is characterised in that it consists in reacting in an aqueous medium a diazonium salt of an aromatic diphenyl compound with a disulphide sulphur compound, in the presence of an efficient amount of a coupling catalyst.

Liquid-phase oxidation of thiols with chlorine dioxide

The products and kinetics of the liquid-phase oxidation of 11 aliphatic and aromatic thiols with chlorine dioxide were studied at -10-+70 °C in organic media. The rate constants and activation parameters of the reaction were determined. The influence of the thiol structure on its reactivity was studied. A strong solvent effect on the reaction rate constant was found, and the reaction mechanism was proposed.
