General Description

Trimethylsulfonium bromide is a quaternary ammonium salt with the chemical formula (CH3)3SBr. It is a colorless to pale yellow crystalline solid that is soluble in water and organic solvents. Trimethylsulfonium bromide is commonly used as a phase-transfer catalyst in organic synthesis and as a methylating agent in chemical reactions. It is also used in the synthesis of pharmaceuticals and as a reagent in the preparation of organic compounds. Additionally, it has been studied for its potential anti-inflammatory and antioxidant properties. Overall, trimethylsulfonium bromide is an important chemical reagent with various practical applications in organic chemistry and pharmaceutical research.

Check Digit Verification of cas no

The CAS Registry Mumber 3084-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,8 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3084-53:
(6*3)+(5*0)+(4*8)+(3*4)+(2*5)+(1*3)=75
75 % 10 = 5
So 3084-53-5 is a valid CAS Registry Number.

Influence of Temperature on the Liquid-Liquid Equilibrium of the Ternary System Acetonitrile-2-Furyloxirane-Cyclohexane

Rakotondramanana, Samuel,Borredon, Marie-Elisabeth,Molinier, Jacques

, p. 306 - 308 (1987)

2-Furyloxirane can be obtained by a low hydrated solid-liquid phase transfer process from furfural and a sulfonium salt in basic medium by using acetonitrile as a solvent.It is purified by extraction in a reactive medium with an extracting solvent, cyclohexane.Diagrams on solubility isotherms and tie-line data are given for the ternary system acetonitrile-2-furyloxirane-cyclohexane at 20-30 and 40 deg C.Under these conditions 2-furyloxirane extraction by cyclohexane appears not to depend on temperature.

Redox-Divergent Construction of (Dihydro)thiophenes with DMSO

Chen, Qing-An,He, Gu-Cheng,Hu, Yan-Cheng,Ji, Ding-Wei,Liu, Heng,Zhang, Xiang-Xin,Zhao, Chao-Yang

supporting information, p. 24284 - 24291 (2021/10/08)

Thiophene-based rings are one of the most widely used building blocks for the synthesis of sulfur-containing molecules. Inspired by the redox diversity of these features in nature, we demonstrate herein a redox-divergent construction of dihydrothiophenes, thiophenes, and bromothiophenes from the respective readily available allylic alcohols, dimethyl sulfoxide (DMSO), and HBr. The redox-divergent selectivity could be manipulated mainly by controlling the dosage of DMSO and HBr. Mechanistic studies suggest that DMSO simultaneously acts as an oxidant and a sulfur donor. The synthetic potentials of the products as platform molecules were also demonstrated by various derivatizations, including the preparation of bioactive and functional molecules.
