97675-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97675-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,7 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97675-21:
(7*9)+(6*7)+(5*6)+(4*7)+(3*5)+(2*2)+(1*1)=183
183 % 10 = 3
So 97675-21-3 is a valid CAS Registry Number.

Base-catalyzed stereoselective hydrophenoxylation and hydrothiolation of hexafluorobutyne

Bo, Zhao,Dong-Huai, Tu,Ji-Jun, Zeng,Jian, Lu,Jiang-Wei, Li,Sheng, Han,Wei, Zhang

supporting information, (2020/02/11)

Novel base-catalyzed hydrophenoxylation and hydrothiolation of hexafluorobutyne are described. By using an easily available base, a variety of vinyl ethers as well as sulfides are prepared at room temperature through two-phase nucleophilic addition reacti

Chemistry of Halogenoperfluoroalkanes> Synthesis of Fluorinated Ethers and Thioethers via Radical or Anionic Intermediates

Wakselman, Claude,Tordeux, Marc

, p. 4047 - 4051 (2007/10/02)

Condensation of bromotrifluoromethane with potassium thiophenoxides in DMF is performed under pressure (2-3 atm) in a glass apparatus.Inhibition by nitrobenzene shows that a SRN1 mechanism is involved in the formation of aryl trifluoromethyl sulfides.Dichlorodifluoromethane itself reacts through a similar process to give aryl chlorodifluoromethyl sulfides.Condensation of 1,1,2-trichlorotrifluoroethane with potassium thiophenoxide or phenoxide occurs even in the presence of nitrobenzene.The formation of aryl 2,2-dichloro-1,1,2-trifluoroethyl sulfides or ethers can be explained by a chain carbanionic mechanism.
