33174-74-2 Usage

General Description

2,2'-Dithiobis(benzonitrile) is a chemical compound used as a crosslinking agent in the production of polymers and resins. It contains two benzene rings connected by a sulfur bridge, and is commonly used in the manufacturing of rubber and plastics. The compound is also utilized in the synthesis of pharmaceuticals and as a building block in organic chemistry. 2,2'-Dithiobis(benzonitrile) has high thermal stability and is insoluble in water, making it suitable for a variety of industrial applications. However, it is important to handle this chemical with caution due to its potential health hazards and environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 33174-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,7 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33174-74:
(7*3)+(6*3)+(5*1)+(4*7)+(3*4)+(2*7)+(1*4)=102
102 % 10 = 2
So 33174-74-2 is a valid CAS Registry Number.

Synthesis of Functionalized Diaryl Sulfides by Cobalt-Catalyzed Coupling between Arylzinc Pivalates and Diaryl Disulfides

Dong, Zhi-Bing,Balkenhohl, Moritz,Tan, Eric,Knochel, Paul

supporting information, p. 7581 - 7584 (2018/11/27)

An efficient protocol for the cobalt-catalyzed preparation of diaryl sulfides from solid organozinc pivalates and commercially available diaryl disulfides is reported. This cross-coupling proceeds at room temperature and displays a good functional group tolerance, allowing the preparation of a diversity of symmetrical or asymmetrical diaryl sulfides in 60-95% yield.

Gas-phase cyclisation reactions of 1-(2-arylthiophenyl)alkaniminyl and 2-(aryliminomethyl)thiophenoxyl radicals

Creed,Leardini,McNab,Nanni,Nicolson,Reed

, p. 1079 - 1085 (2007/10/03)

Flash vacuum pyrolysis (FVP) of the oxime ethers 12-14 and of the sulfides 18-20 at 650°C (10-2-10-3 Torr) gave products derived from the corresponding iminyl and thiophenoxyl radicals. In all cases, benz[d]isothiazoles (e.g., 26) are formed as major products via SHi mechanisms though the yields are greatest with the iminyl precursors. Alternative pathways observed from the thiophenoxyls in specific cases include the formation of the anilinobenzothiophene 36 and of dibenzothiophene 23, via an SHi process and a spirodienyl rearrangement, respectively. There is no evidence for signicant interconversion of the iminyl and thiophenoxyl species.
