692-49-9 Usage

Uses

Z-1,1,1,4,4,4-Hexafluoro-2-butene is a useful compound in regards to heat transfer applications due to the stability of the carbon fluorine bond.

Check Digit Verification of cas no

The CAS Registry Mumber 692-49-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 692-49:
(5*6)+(4*9)+(3*2)+(2*4)+(1*9)=89
89 % 10 = 9
So 692-49-9 is a valid CAS Registry Number.

Synthesis of bis(trifluoromethyl)alkylated trisubstituted alkenes via highly regioselective catalyzed hydrosilylation reaction of hexafluoro-2-butyne and their reactivity

Filatov, Andrey A.,Jackson, Andrew,Kirij, Nataliia V.,Peng, Sheng,Yagupolskii, Yurii L.

, (2021/11/24)

Hydrosilylation reaction of hexafluoro-2-butyne 1 (HFB) with various silanes in the presence of a catalytic amount of transition-metal-catalysts was investigated. The reaction of HFB gave the corresponding bis(trifluoromethyl)containing vinylsilanes in an excellent regioselective manner in high yields. Treatment of the resulting vinylsilanes with various aldehydes and ketones in the presence of fluoride ion sources afforded the coupling products in moderate yields.

METHOD OF HYDRODECHLORINATION TO PRODUCE DIHYDROFLUORINATED OLEFINS

-

Page/Page column 4, (2010/07/04)

Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkene with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkene with hydrogen to produce a fluorine-containing olefin, wherein said catalyst is a composition comprising chromium, nickel and optionally an alkali metal selected from potassium and cesium. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkenes comprising copper, nickel, and an alkali metal selected from potassium and cesium, and methods of making such catalysts.
