Chemical Description

Trifluoromethanesulfonic acid is an organic compound with the formula CF3SO3H.

Description

Trifluoromethanesulfonic acid, also known as triflic acid, TFMS, TFSA, HOTf or TfOH, is a sulfonic acid with the chemical formula CF3SO3H. It is often regarded as one of the strongest acids, and is one of a number of so-called "superacids". it is used in the manufacture of pharmaceuticals, agricultural chemicals and polymers. The anhydrous form is widely used in fine chemical synthesis. It is non-oxidizing, has a high thermal stability, and is resistance to both oxidation and reduction, which makes it one of the more useful compounds in the super acids class. In the pharma industry, it is used to make a number of drug classes, including nucleosides, antibiotics, steroids, proteins and glycosides. Triflic anhydride reacts readily with water and has an unfavorable toxicity profile.

Chemical Properties

Different sources of media describe the Chemical Properties of 1493-13-6 differently. You can refer to the following data:
1. Trifluoromethanesulfonic acid is a hygroscopic, colorless liquid at room temperature. It is soluble in polar solvents such as dimethylformamide (DMF), dimethyl sulfoxide (DMSO), acetonitrile, and dimethyl sulfone. Addition of triflic acid to polar solvents can be dangerously exothermic. Trifluoromethanesulfonic acid is widely used especially as a catalyst and a precursor in organic chemistry. With an Ka = 8. 0 1014 (pKa ~ -15) mol/kg, HOTf qualifies as a superacid. Triflic acid owes many of its useful properties to its great thermal and chemical stability. Both the acid and its conjugate base CF3SO3-, known as triflate, resist oxidation/reduction reactions, whereas many strong acids are oxidizing, e. g. HClO4 and HNO3. The triflate anion is immune to attack by even strong nucleophiles. Because of its resistance to oxidation and reduction, triflic acid is a very useful and versatile reagent. Further recommending its use, triflic acid does not sulfonate substrates, which can be a problem with sulfuric acid, fluorosulfuric acid, and chlorosulfonic acid. Below is a prototypical sulfonation, which HOTf does not undergo: C6H6 + H2SO4 → C6H5(SO3H) + H2O.
2. Clear very light yellow liquid. Smoke in the air, easy to absorb water to form a hydrate. It is easily soluble in water, releases a lot of heat, and hydrolyzes to generate trifluoromethane (CHF3) and sulfuric acid.

Preparation

Yellow-brown liquid. The boiling point is 167~170 ℃.The refractive index is 1.331.The relative density is 1.708.It is the strongest organic acids, easily soluble in water.Use carbon disulfide as raw material, with the reaction of iodine pentafluoride to produce trifluoromethyl disulfide.(CF3S) 2Hg was obtained when reacting with mercury; Then through oxidation of hydrogen oxide, trifluoromethanesulfonic acid is acquired.

Uses

Different sources of media describe the Uses of 1493-13-6 differently. You can refer to the following data:
1. It is used for organic synthesis, widely used in pharmaceutical and chemical industries, such as nucleosides, antibiotics, steroids, protein, sugar, vitamins synthesis, silicone rubber modification. Isomerization and alkylation of the catalyst, the preparation of 2, 3-dihydro-2-indanone, tetralone, glycosides in the removal of glycoproteins.
2. As a catalyst in Friedel-Crafts type acylation, alkylation and polymerization reactions; as a solvent for ESR; as a nonaqueous strong acid titrant; with trifluoroacetic acid, q.v., in solid-phase peptide synthesis. One of the strongest available monoprotic acids.
3. Trifluoromethanesulfonic acid acts as a catalyst for esterification reactions and an acidic titrant in nonaqueous acid-base titration. It is useful in protonations due to the presence of conjugate base triflate is non nucleophilic. It serves as a deglycosylation agent for glycoproteins. In addition, it is a precursor and a catalyst in organic chemistry. It reacts with acyl halides to prepare mixed triflate anhydrides, which are strong acylating agents used in Friedel-Crafts reactions. It acts as a key starting material for the preparation of ethers and olefins by reacting with alcohols as well as to prepare trifluoromethanesulfonic anhydride by dehydration reaction.

It acts as a key starting material for the preparation of ethers and olefins by reacting with alcohols as well as to prepare trifluoromethanesulfonic anhydride by dehydration reaction. Catalyst used in the production of cocoa butter substitute from palm oil. This is a very similar reaction to what would be done if one wanted to create polymers using triflic acid in the synthesis. Other Friedel-Crafts type reactions using triflic acid include cracking of alkanes and alkylation of alkenes which are very important to the petroleum industry. These triflic acid derivative catalysts are very effective in isomerizing straight chain or slightly branched hydrocarbons that can increase the octane rating of a particular petroleum based fuel.

Definition

ChEBI: Trifluoromethanesulfonic acid is a one-carbon compound that is methanesulfonic acid in which the hydrogens attached to the methyl carbon have been replaced by fluorines. It is a one-carbon compound and a perfluoroalkanesulfonic acid. It is a conjugate acid of a triflate.

General Description

Trifluoromethanesulfonic acid is a strong organic acid. It can be prepared by reacting bis(trifluoromethylthio)mercury with H2O2. On mixing with HNO3, it affords a nitrating reagent (a nitronium salt). This reagent is useful for the nitration of aromatic compounds. Its dissociation in various organic solvents has been studied.

Safety Profile

A corrosive irritant to the skin, eyes, and mucous membranes. A strong acid. Violent reaction with acyl chlorides or aromatic hydrocarbons evolves toxic hydrogen chloride gas. When heated to decomposition it emits toxic fumes of Fand SOx. See also FLUORIDES.

Check Digit Verification of cas no

The CAS Registry Mumber 1493-13-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,9 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1493-13:

The vibrational spectrum of trifluoromethanesulphonic acid, CF3SO3H, and the determination of its degrees of discociation in aqueous solution by Raman spectroscopy

Edwards, H. G. M.

, p. 715 - 720 (1989)

The Raman and i.r. spectra of trifluoromethanesulphonic acid, CF3SO3H, have been obtained, and vibrational assignments made which are consistent with Cs molecular symmetry.The degrees of dissociation of CF3SO3H in aqueous solution in the concentration range 1.8-11.1 M were determined from Raman intensity measurements on the Δν = 1034 cm-1 band characteristic of the CF3SO3- ion.The results confirm that CF3SO3H is more dissociated into CF3SO3- ions than CH3SO3H is into CH3SO3- at similar concentrations.A limiting value of Kc = 280 mol dm-3 is calculated for low acid concentrations of CF3SO3H.

Thermodynamics of methanesulfonic acid revisited

Guthrie,Gallant

, p. 1295 - 1298 (2000)

Recently we reported a study of the thermodynamics of methanesulfonic acid and some of its derivatives. The foundation of these results was a measurement of the heat of reaction of S-methyl thioacetate with aq sodium hypochlorite, leading to methanesulfonic acid. We have reinvestigated this reaction and discovered that contrary to the initial stoichiometry experiments, the stoichiometry under the reaction conditions is not as was believed and that the heat of reaction observed was spuriously high. We have found a new reaction, that of sulfite ion with methyl methanesulfonate, which does allow a clean determination of the heat of formation of methanesulfonic acid. Revised thermodynamic quantities for methanesulfonic acid, methanesulfonyl chloride, and methyl methanesulfonate are reported here.

SYNTHESIS OF TRIFLUOROMETHANESULFONATE ESTERS BY REATION OF ALKYL CHLORIDES WITH CHLORINE (I) AND BROMINE (I) TRIFLUOROMETHANESULFONATE

Katsuhara,Yutaka,Desmarteau, Darryl D.

, p. 257 - 264 (1980)

The synthesis of the first trifluoromethanesulfonate esters of the type CF3SO3(CH2)nO3SCF3(n=1,2,3) are reported.The new compounds are prepared from Cl(CH2)nCl by substitutive electrophilic dehalogenation reactions with CF3SO2OX (x=Cl,Br).The extension of this reaction to HCCl3 results in HC(O3SCF3)3 but the compound is unstable at 22 deg.

Remarkable Acid Catalysis in Proton-Coupled Electron-Transfer Reactions of a Chromium(III)-Superoxo Complex

Devi, Tarali,Lee, Yong-Min,Nam, Wonwoo,Fukuzumi, Shunichi

, p. 8372 - 8375 (2018)

Much enhanced acid catalysis was observed in oxygen atom transfer (OAT) reactions by a mononuclear nonheme Cr(III)-superoxo complex, [(Cl)(TMC)CrIII(O2)]+ (1), in the presence of triflic acid. In the acid-catalyzed reactions, the reactivity of 1 in OAT of thioanisole was enhanced significantly, showing more than 104-fold acceleration in rate. Electron transfer (ET) from electron donors to 1 also occurred only in the presence of HOTf. The enhanced reactivity of 1 by HOTf was explained by proton-coupled electron transfer from electron donors, such as ferrocene, to 1 in light of the Marcus theory of ET. The present study reports for the first time the dramatic proton effect on the chemical properties of metal-superoxo species.

Synthesis of trifluoromethanesulfonic acid from CHF3

Mukhopadhyay, Sudip,Bell, Alexis T.,Vijay Srinivas,Smith, Gary S.

, p. 660 - 662 (2004)

Trifluoromethane is transformed to trifluoromethanesulfonic acid (TFMSA) at low temperature in a liquid-phase reaction in a strong acid such as fuming sulfuric acid as well as in a strong basic solution such as t-BuOK/DMF.

Water determines the products: An unexpected Br?nsted acid-catalyzed PO-R cleavage of P(iii) esters selectively producing P(O)-H and P(O)-R compounds

Li, Chunya,Wang, Qi,Zhang, Jian-Qiu,Ye, Jingjing,Xie, Ju,Xu, Qing,Han, Li-Biao

supporting information, p. 2916 - 2922 (2019/06/18)

Water is found able to determine the selectivity of Br?nsted acid-catalyzed C-O cleavage reactions of trialkyl phosphites: with water, the reaction quickly takes place at room temperature to afford quantitative yields of H-phosphonates; without water, the reaction selectively affords alkylphosphonates in high yields, providing a novel halide-free alternative to the famous Michaelis-Arbuzov reaction. This method is general as it can be readily extended to phosphonites and phosphinites and a large scale reaction with much lower loading of the catalyst, enabling a simple, efficient, and practical preparation of the corresponding organophosphorus compounds. Experimental findings in control reactions and substrate extension as well as preliminary theoretical calculation of the possible transition states all suggest that the monomolecular mechanism is preferred.
