General Description

4-Methylphenylsulphur pentafluoride is a chemical compound with the molecular formula C7H5F5S. It is a sulfur pentafluoride derivative with a methylphenyl group attached to the sulfur atom. 4-Methylphenylsulphur pentafluoride is commonly used as a reagent in organic synthesis and has been utilized in the preparation of various fluorinated compounds. It is a colorless liquid with a pungent odor and has been reported to act as a highly reactive and powerful fluorinating agent. Due to its potential hazards and reactivity, proper handling and storage procedures should be followed when working with 4-Methylphenylsulphur pentafluoride.

Check Digit Verification of cas no

The CAS Registry Mumber 203126-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,1,2 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 203126-21:
(8*2)+(7*0)+(6*3)+(5*1)+(4*2)+(3*6)+(2*2)+(1*1)=70
70 % 10 = 0
So 203126-21-0 is a valid CAS Registry Number.

AgBF4-Mediated Chlorine-Fluorine Exchange Fluorination for the Synthesis of Pentafluorosulfanyl (Hetero)arenes

Tanagawa, Kazuhiro,Zhao, Zhengyu,Saito, Norimichi,Shibata, Norio

, p. 1682 - 1684 (2021/07/19)

We report a new protocol to form pentafluorosulfanyl (hetero)arenes via chlorine-fluorine exchange of (hetero)aryl tetrafluorosulfanyl chlorides by AgBF4. The method enables access to electron-deficient pentafluorosulfanyl(hetero)arenes, which are targets that are difficult to synthesize. Two advantages of AgBF4 are its ease of handling and stability. This would be a general transformation protocol.

IF5 affects the final stage of the Cl-F exchange fluorination in the synthesis of pentafluoro-λ6-sulfanyl-pyridines, pyrimidines and benzenes with electron-withdrawing substituents

Cui, Benqiang,Kosobokov, Mikhail,Matsuzaki, Kohei,Tokunaga, Etsuko,Shibata, Norio

, p. 5997 - 6000 (2017/07/10)

A difficult chlorine-fluorine (Cl-F) exchange fluorination reaction in the final stage of the preparation of pentafluoro-λ6-sulfanyl-(hetero)arenes having electron-withdrawing substituents has now been elucidated through the use of iodine pentafluoride. A major side-reaction of C-S bond cleavage was sufficiently inhibited by the potential interaction between F and I with a halogen bonding.

Discovery of practical production processes for arylsulfur pentafluorides and their higher homologues, bis- and tris(sulfur pentafluorides): Beginning of a new era of "super-trifluoromethyl" arene chemistry and its industry

Umemoto, Teruo,Garrick, Lloyd M.,Saito, Norimichi

, p. 461 - 471 (2012/07/01)

Various arylsulfur pentafluorides, ArSF5, have long been desired in both academic and industrial areas, and ArSF5 compounds have attracted considerable interest in many areas such as medicines, agrochemicals, and other new materials, since the highly stable SF5 group is considered a "super-trifluoromethyl group" due to its significantly higher electronegativity and lipophilicity. This article describes the first practical method for the production of various arylsulfur pentafluorides and their higher homologues, bis- and tris(sulfur pentafluorides), from the corresponding diaryl disulfides or aryl thiols. The method consists of two steps: (Step 1) treatment of a diaryl disulfide or an aryl thiol with chlorine in the presence of an alkali metal fluoride, and (step 2) treatment of the resulting arylsulfur chlorotetrafluoride with a fluoride source, such as ZnF2, HF, and Sb(III/V) fluorides. The intermediate arylsulfur chlorotetrafluorides were isolated by distillation or recrystallization and characterized. The aspects of these new reactions are revealed and reaction mechanisms are discussed. As the method offers considerable improvement over previous methods in cost, yield, practicality, applicability, and large-scale production, the new processes described here can be employed as the first practical methods for the economical production of various arylsulfur pentafluorides and their higher homologues, which could then open up a new era of "super-trifluoromethyl" arene chemistry and its applications in many areas.
