Methyl trifluoromethane sulfonic acid

Triflucrcrrsethanesuifonate, FNHj FjCSOj, mp subl CA Registry No 42138-65-5. It is prepd by the reaction of N-fluorourethane with trifluoromethanesulfonic acid in methyl chloride (Ref 6). It is more stable than the salts listed above (Ref 6), and upon subln at low press, it dissociates into fluoramine and trifluoromethane-sulfonic acid without further decompn (Ref 7) Refs 1)0. Ruff L.

There are reports that doped CPs are soluble in unusual solvents, which are difficult to handle for many reasons. Polyaniline dissolves in concentrated acids such as sulfuric acid, methane, and trifluoromethane sulfonic acids concentrations as high as 20% by weight are possible. After precipitation of the polymer in methyl alcohol, the polymer retains its conductivity and exhibits some crystallinity. And recently, MacDiarmid and others have spun fibers from concentrated H2SO4 solutions.

Mes) is comparable to those found for related Mo (II) NHC complexes [119]. The reaction of the complexes 62 with electrophilic reagents such as trifluoromethane-sulfonic acid or methyl trifluoromethanesulfonate led to the formation of the classical NHC complexes (63 and 64, Scheme 14.32) via a protonation (or alkjdation) of the noncoordinated N atom.

Polymerization of Methyl 4-(phenylthio)phenyl Sulfoxide. Poly[methyl[4-(phenylthio)phenyl] sulfonium trifluoromethane sulfonate](PPST), A 100 mL, round-bottom flask with a Teflon-covered magnetic stirring bar was charged with methyl 4-(phenylthio)phenyl sulfoxide (1 g, 4 mmol). The flask was cooled to 0 <>C. Trifluoromethane sulfonic acid (5 mL) was added at 0 <>C with stirring. The temperature was increased slowly to room temperature over a period of 0.5 -1 h. The reaction solution turned from colorless to pale blue. The reaction are continued for another 20 h at room temperature. The reaction was then quenched by pouring it into ice water. The precipitated polymer was then chopped in a blender, washed with water, and dried in vacuum at room temperature for 20 h. Yield 1.53 g (100%). IR (KBr, cm-i) 3086,... 

The same authors studied the CL of 4,4,-[oxalylbis(trifluoromethylsulfo-nyl)imino]to[4-methylmorphilinium trifluoromethane sulfonate] (METQ) with hydrogen peroxide and a fluorophor in the presence of a, p, y, and heptakis 2,6-di-O-methyl P-cyclodextrin [66], The fluorophors studied were rhodamine B (RH B), 8-aniline-l-naphthalene sulfonic acid (ANS), potassium 2-p-toluidinylnaph-thalene-6-sulfonate (TNS), and fluorescein. It was found that TNS, ANS, and fluorescein show CL intensity enhancement in all cyclodextrins, while the CL of rhodamine B is enhanced in a- and y-cyclodextrin and reduced in P-cyclodextrin medium. The enhancement factors were found in the range of 1.4 for rhodamine B in a-cyclodextrin and 300 for TNS in heptakis 2,6-di-O-methyl P-cyclodextrin. The authors conclude that this enhancement could be attributed to increases in reaction rate, excitation efficiency, and fluorescence efficiency of the emitting species. Inclusion of a reaction intermediate and fluorophore in the cyclodextrin cavity is proposed as one possible mechanism for the observed enhancement. 

Pyruvate ketals can be synthesized [161] by direct condensation of a pyruvate ester with a diol in the presence of a Lewis acid, but this is less preferred because of the electron-withdrawing effect of the adjacent carboxylate group [162,163]. Therefore, several indirect methods for the acetalization have been introduced including condensation with pyruvate derivatives [164,165] or generation of the carboxylate group by oxidation of a suitable precursor [166,167,168,169]. A more efficient route to pyruvic acid acetals starts from silylated diols [170] or by the reaction between diols and methyl pyruvate dialkyl dithioacetal [171,172] activated by methyl triflate, dimethyl(methylthio)sulfonium trifluoromethane sulfonate (DMTST), nitroso tetraflu-oroborate (NOBF4), S02Cl2-trifluoromethanesulfonic acid, or Al-Iodosuccinimide (NIS) and trifluoromethanesulfonic acid [173] (O Scheme 24).
