A very simple method for the preparation of symmetrical disulfides

Addition of sulfuryl chloride to an alkyl- or arylthiol in a 1:2 ratio under solvent free conditions or in CH2Cl2 solution produces the corresponding disulfides in nearly quantitative yields. A serendipitiously discovered, extremely simple, fast and previously unreported method for the preparation of symmetrical aliphatic, aromatic and heteroaromatic disulfides is reported. Addition of sulfuryl chloride to an alkyl- or arylthiol in a 1:2 ratio under solvent free conditions or in dichloromethane solution produces the corresponding disulfides in nearly quantitative yields with the concomitant elimination of gaseous SO2 and 2 equiv of HCl. Thus, optimally the reaction needs no work-up at all leaving the disulfide as the sole product in excellent yield. In dichloromethane solution, the reaction is conveniently carried out in a rotary evaporator by mixing the solvent, thiol and SO2Cl2 in a round-bottomed flask followed by evaporation of the volatiles.

Oxidative dehydrogenation of thiols to disulfides at room temperature using silica supported iron oxide as an efficient solid catalyst

Selective transformation of thiols to disulfides by means of oxidative dehydrogenation has been described using silica supported iron oxide under base- and solvent-free reaction conditions at room temperature in an open atmosphere. The easiness of catalyst preparation, green reaction conditions, easy separation of the formed products and catalyst from the reaction mixture, and recyclability of the catalyst, are the most attractive facets of our synthetic procedure which, being ecofriendly, will find immense applications in academic and industrial sectors.

Iron(III)-Ethylenediaminetetraacetic Acid Mediated Oxidation of Thiols to Disulfides with Molecular Oxygen

FeIIIEDTA in aqueous methanol offers a simple environmentally acceptable synthetic tool for oxidizing thiols to the corresponding disulfides by molecular oxygen in excellent yields, under mild conditions and devoid of side reactions.

Silica-supported ICl as a novel heterogeneous system for the rapid and selective oxidation of thiols to symmetrical disulfides

ICl-SiO2 as a new reactive system was prepared by treatment of iodine monochloride with activated silica gel in chloroform. ICl-SiO2 in a heterogeneous system efficiently converted thiols to the corresponding disulfides under mild conditions in high yields at room temperature.[image omitted].

Simple and green method for synthesis of symmetrical dialkyl disulfides and trisulfides from alkyl halides in water; PMOxT as a sulfur donor

An environmentally new, mild and efficient method has been developed for the synthesis of dialkyl disulfides and dialkyl trisulfides in aqueous conditions by a reaction between alkyl halides (and tosylate) and potassium-5-methyl-1,3,4-oxadiazole-2-thiolate (PMOxT) as a sulfur transfer reagent. The advantages of this method are that it occurs under mild reaction conditions, it is base free, it uses water as the solvent and it occurs in high yields. A variety of dialkyl disulfides and dialkyl trisulfides can be obtained in good to excellent yields up to 98%.

Preparation and characterization of long-chain di-n-alkyl disulfides

The preparation of long-chain symmetric di-n-alkyl disulfides based on the reaction of BUNTE SALTS (RS2O3Na) with iodine is reported. 1H-NMR, FT-IR, and FT-RAMAN spectra of the solid and liquid/molten aliphatic title disulfides were recorded. An assignment of the vibrational frequencies is proposed especially in regard to the S-S and C-S vibrations. Distinct spectral differences are determined between the solid and liquid state, as well as between disulfides with even and those with odd numbered alkyl substituents, respectively. The observed phenomena are ascribed to different species in the solids and liquids/melts and their respective VAN DER WAALS interactions. In addition, mass spectra, GC-MS studies, as well as the thermal behaviour of the disulfides, based on investigations by DSC and TGA, are reported.

Application of ionic liquids for extraction and synthesis of organosulfur compounds

We consider the possible application of pyridinium ionic liquids to desulfurize hydrocarbon raw products and to transform the extracted toxic admixtures into promising sulfur compounds. Anodic oxidation of the extracted thiols as well as oxidation in the presence of electron mediators (N,N,N′,N′-tetramethyl-1,4-phenylenediamine, tri-p-bromophenylamine, and tri-p-tolylamine) leads to the corresponding disulfides.

Substituted o-Aminophenols as Redox-Mediators in the Thiol Oxidation to Unsymmetrical Disulfides

A number of substituted o-aminophenols has been investigated as redox mediators of the thiol oxidation to disulfides. The electrooxidation of o-aminophenols leads to the corresponding o-iminobenzoquinones. These compounds react with thiols in the solution with a formation of disulfides. It was established that the use of 4,6-di-tert-butyl-2-(tert-butylamino)phenol as a redox mediator can reduce the overpotential of the thiol oxidation by 0.2-1.4 V depending on the nature of the coupling thiols. The unsymmetrical disulfides with alkyl, aryl, and heteroaryl substituents were obtained as the result of the indirect electrosynthesis.
