2905-17-1 Usage

General Description

Di(2,6-xylyl) disulphide, also known as DIDS, is a chemical compound that consists of two 2,6-xylyl groups linked by a disulphide bond. It is commonly used as a cross-linking agent, particularly in rubber compounds, where it helps to improve the physical properties and stability of the material. DIDS is also used as an anti-corrosive agent and as a vulcanization accelerator in the production of rubber. Additionally, it can act as a cross-linking agent in the synthesis of polymers, where it helps to enhance the strength and durability of the resulting materials. Due to its versatile applications, DIDS is widely used in the manufacturing of various industrial and consumer products. However, it is important to handle DIDS with care, as it can be harmful if ingested or inhaled, and it may cause skin and eye irritation upon contact.

Check Digit Verification of cas no

The CAS Registry Mumber 2905-17-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2905-17:
81 % 10 = 1
So 2905-17-1 is a valid CAS Registry Number.

Reaction of organic disulfides with cobalt-centered metal radicals. Use of the E- and C-based dual-parameter substituent model and quantitative solvent effect analyses to compare outer-sphere and inner-sphere electron- transfer processes

Aubart, Mark A.,Bergman, Robert G.

, p. 8755 - 8766 (1998)

Treatment of isolable, paramagnetic Cp2Ta(μ-CH2)2CoCp (1, Cp = η5- C5H5) with aromatic disulfides RSSR affords diamagnetic monothiolate complexes Cp2Ta(μ-CH2)2Co(SR)Cp in quantitative yield. The structure of Cp2Ta(μ-CH2)2Co(SC6H3(CH3)2)Cp (2a) has been characterized by X-ray crystallography. The mechanism of this disulfide S-S bond cleavage reaction has been probed using kinetic, substituent effect, and solvent effect techniques. A Hammett σ/ρ substituent constant analysis yields a nonlinear correlation. In contrast, application of the E- and C-based dual-parameter substituent model gives a good fit of the data and demonstrates that the reaction is sensitive to both the electrostatic and the covalent characteristics of the entering disulfide. All substituents examined (excluding p-(trifluoromethyl)phenyl) exhibited a solvent effect consistent with a modest amount of charge separation in the transition state. The reaction of 1 with the strongly electron withdrawing substituted bis[p- (trifluoromethyl)phenyl] disulfide is much more sensitive to solvent polarity changes. As a comparison system expected to proceed via a limiting outer- sphere electron-transfer mechanism, the reaction of aromatic disulfides with the 19-electron complex cobaltocene (CoCp2, 3), which leads to salts [CoCp2][SR] (4), was investigated using methods parallel to those employed in the study of Ta/Co complex 1. In the cobaltocene system, the kinetic, solvent effect, and substituent effect data showed that the reaction is especially sensitive to the electrostatic character of the disulfide and relatively insensitive to its Covalent character and steric bulk. The comparison of cobaltocene with Ta/CO complex 1 shows that the latter reacts with most diaryl disulfides (perhaps with the exception of p-CF3 compound 2f, which may be a borderline case) via a transition state with substantially more covalent character, and correspondingly less charge separation. than that involved in the outer-sphere reactions of Cp2Co.

Metal-free chalcogenation of cycloketone oxime esters with dichalcogenides

Ji, Liangshuo,Qiao, Jiamin,Liu, Junjie,Tian, Miaomiao,Lu, Kui,Zhao, Xia

supporting information, (2021/06/15)

We report the metal-free chalcogenation of cycloketone oxime esters with dichalcogenides via a radical process. Because of the metal-free condition and use of readily accessible dichalcogenides, this method is an effective and green strategy for the synthesis of chalcogen-substituted butyronitrile.

Transformation of arylboronic acids with sodium thiosulfate into organodisulfides catalyzed by a recyclable polyoxometalate-based Cr(iii) catalyst

Chang, Yalin,Li, Huiyi,Tao, Chaofu,Wang, Aiping,Wei, Yongge,Xie, Ya,Yu, Han,Yu, Shunming

supporting information, p. 6059 - 6064 (2021/08/23)

Organo disulfides represent an abundant class of compounds in chemical biology, pharmaceutical fields, and industry. They are traditionally synthesized by the oxidation of mercaptan in the presence of an organic ligand supported metal catalyst or toxic oxidants under harsh conditions. Here, we disclose a highly-efficient pathway in which disulfide is synthesized by organic boric acid and Na2S2O3 using the catalyst (NH4)3[CrMo6O18(OH)6], demonstrating a high activity and excellent selectivity. Various boric acid derivatives have been successfully transformed into the corresponding disulfides. Mechanistic insights have been furnished based on the observation of intermediate and control experiments.

Diacetoxyiodobenzene mediated oxidative transformation of thione to disulfides

Singh, Sarangthem Joychandra,Devi, Nepram Sushuma

supporting information, p. 5941 - 5943 (2016/12/07)

We have developed an efficient oxidative transformation of thione to disulfides using diacetoxyiodobenzene (DIB) in acetonitrile at room temperature. This strategy is suited for oxidation of thiols to disulfide also. The present oxidation protocol is mild reaction condition, column free, and a new route for disulfide formation.
