Carbamimidic fluoride, tris(trifluoromethyl)-, also known as N,N,N-trifluoromethyl-N-(trifluoromethylsulfonyl)carbamoyl fluoride or TFMS-COF, is a highly reactive and potent chemical compound. It is a colorless, crystalline solid with the molecular formula C4F9NO2S and a molecular weight of 259.09 g/mol. Carbamimidic fluoride, tris(trifluoromethyl)- is widely used as a reagent in organic synthesis, particularly for the preparation of various fluorinated compounds and as a fluorinating agent. Due to its high reactivity and potential toxicity, it is essential to handle this chemical with extreme caution and in a controlled environment.

686-39-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 686-39-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 686-39:
(5*6)+(4*8)+(3*6)+(2*3)+(1*9)=95
95 % 10 = 5
So 686-39-5 is a valid CAS Registry Number.

Three prototypical fluoroaryliodonium salts with the [N(CF 3)2]- anion were obtained by metathesis in the corresponding tetrafluoroborate salts [Ar(Ar′)I][BF4] (Ar/Ar′ = C6H5/4-FC6/su

A convenient synthesis of N,N-bis(trifluoromethyl)anilines

Hirschberg,Ignat'Ev,Wenda,Frohn,Willner

body text, p. 176 - 182 (2012/03/27)

A convenient synthesis of N,N-bis(trifluoromethyl)anilines by means of dediazotation reactions of previously unknown aryldiazoniumbis(trifluoromethyl) imides in the presence of CuI salts are described. Properties and applications of N,N-bis(trifluoromethyl)anilines in syntheses of aromatic compounds containing the (CF3)2N group are presented.
