1-Chloro-3-(vinylsulfonyl)benzene is an organic chemical compound with the molecular formula C8H7ClO2S. It is a colorless to pale yellow liquid that is soluble in organic solvents. 1-chloro-3-(vinylsulfonyl)benzene is characterized by the presence of a chloro group (-Cl) at the 1st carbon position, a vinylsulfonyl group (-CH=CH-SO2-) at the 3rd carbon position, and a benzene ring. It is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, it is essential to handle 1-chloro-3-(vinylsulfonyl)benzene with care, following proper safety protocols and guidelines.

5535-43-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5535-43-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,3 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5535-43:
(6*5)+(5*5)+(4*3)+(3*5)+(2*4)+(1*3)=93
93 % 10 = 3
So 5535-43-3 is a valid CAS Registry Number.

Diastereoselective Monofluorocyclopropanation Using Fluoromethylsulfonium Salts

Melngaile, Renate,Sperga, Arturs,Baldridge, Kim K.,Veliks, Janis

, p. 7174 - 7178 (2019/09/12)

Diarylfluoromethylsulfonium salts, alternatives to freons or advanced fluorinated building blocks, are bench stable and easy-to-use sources of direct fluoromethylene (:CHF) transfer to alkenes. These salts enabled development of a trans-selective monofluorinated Johnson-Corey-Chaykovsky reaction with vinyl sulfones or vinyl sulfonamides to access synthetically challenging monofluorocyclopropane scaffolds. The described method offers rapid access to monofluorinated cyclopropane building blocks with further functionalization opportunities to deliver more complex synthetic targets diastereoselectively.
