Styryl(methyl) sulfone, also known as α-Methylstyrene sulfone, is an organic compound with the chemical formula C9H10O2S. It is a colorless to pale yellow crystalline solid that is soluble in organic solvents. Styryl(methyl) sulfone is characterized by a styrene moiety (a phenyl ring with an ethylene group attached) and a methyl sulfone group (a methane molecule with one hydrogen atom replaced by a sulfone group). Styryl(methyl) sulfone is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of certain pesticides and as a precursor in the preparation of other specialty chemicals. Its chemical properties include reactivity towards nucleophiles due to the electron-withdrawing nature of the sulfone group, which can influence its utility in synthetic chemistry.

5342-84-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5342-84-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5342-84:
(6*5)+(5*3)+(4*4)+(3*2)+(2*8)+(1*4)=87
87 % 10 = 7
So 5342-84-7 is a valid CAS Registry Number.

High Chemoselectivity in the Construction of Aryl Methyl Sulfones via an Unexpected C-S Bond Formation between Sulfonylhydrazides and Dimethyl Phosphite

Liu, Teng,Yu, Shiwen,Shen, Xiang,Li, Yixian,Liu, Jianjun,Huang, Chao,Cheng, Feixiang

, p. 153 - 160 (2021/10/04)

A highly chemoselective route to aryl methyl sulfones via an unexpected C S bond formation between sulfonylhydrazides and dimethyl phosphite catalyzed by NaI under mild conditions has been established. This transformation provides an alternative and metal-free pathway to acquire various aryl methyl sulfones in good to excellent yields. Notably, dimethyl phosphite was employed as a stable and readily available alkyl source.

Synthesis of γ-sulfonyl δ-lactones and β-sulfonyl styrenes

Chan, Chieh-Kai,Chen, Yu-Hsin,Hsu, Ru-Ting,Chang, Meng-Yang

, p. 46 - 54 (2016/12/09)

A facile route to the synthesis of γ-sulfonyl lactones 5 and β-sulfonyl styrenes 6 has been developed, achieving moderate to good yields via the (1) NaH mediated Michael addition of β-ketosulfones 3 and methyl acrylate in refluxing THF and (2) NaBH4mediated stereoselective reduction/lactonization of δ-ketoesters 4 in boiling MeOH, or (3) boron trifluoride etherate mediated ring-opening of lactones 5 in MeOH at reflux.

One-pot approach for the regioselective synthesis of β-keto sulfones based on acid-catalyzed reaction of sulfonyl chlorides with arylacetylenes and water

Lai, Chunbo,Xi, Chanjuan,Jiang, Yanfeng,Hua, Ruimao

, p. 513 - 515 (2007/10/03)

Reaction of sulfonyl chlorides with arylacetylenes and water in the presence of a catalytic amount of sulfonic acid in THF provided β-keto sulfones in good yields with excellent regioselectivity.

Sulfonyl Radicals. 7. Kinetics and Mechanism of the Thermal Decomposition of α-Phenylalkanesulfonyl Chlorides Proceeding via Ionic Intermediates
