The RDFs from triflate ion/water mixtures shows that increasing hydration causes water molecules to orient around the SO 3 − group of triflate ions, solvate the hydronium ions, and other water molecules. The diffusion of triflate ions, hydronium ion, and water molecules shows an increase with hydration. At λ = 1, the diffusion of triflate ion is 30 times lower than the diffusion of triflic.

Triflate anions preferentially approach the ammonium cation so as to form strong hydrogen bonds between sulfonate oxygen atoms and the acidic ammonium hydrogen. The ionic conductivity was somewhat underestimated, especially at lower temperatures. Analysis of conductivity data suggests that there is significant correlated motion of oppositely charged ions in these PILs, especially at short. Was sind die Thesauren des Wortes triflate?

Nickelkatalysierte Kreuzkupplungen. Triflate, also known by the systematic name trifluoromethanesulfonate, is a functional group with the formula CF 3 SO 3 −. The triflate group is often represented by −OTf, as opposed to −Tf ().For example, n-butyl triflate can be written as CH 3 CH 2 CH 2 CH 2 OTf. The corresponding triflate anion, CF 3 SO − 3, is an extremely stable polyatomic ion; this comes from the fact that.
Triflate salts. Triflate salts are thermally very stable with melting points up to 350 °C for sodium, boron and silver salts especially in water-free form. They can be obtained directly from triflic acid and the metal hydroxide or metal carbonate in water. Alternatively, they can be obtained from reacting metal chlorides with neat triflic acid or silver triflate, or from reacting barium. triflate name meaning available! triflate name numerology is 1 and here you can learn how to pronounce triflate, triflate origin and similar names to triflate name Triflate, tosylate, and mesylate ions are excellent leaving groups, because the sulfonate ions can stabilize the negative charge via resonance. Good leaving groups are weak bases. These ions are weak bases because they are the conjugate bases of very strong sulfonic acids. But the halide ions Cl⁻, Br⁻, and I⁻ are also good leaving groups. Seven triflate salts differ from mild to strong p-dopant on poly(3-hexylthiophene) sensing micro-arrays. Each material shows a pattern of conductance modulation for the polymer which is reversible, reproducible, and distinctive of other gas exposures. Based on principal component analysis, an array doped with only two different triflates can be trained to reliably discriminate gases, which re.

Indium(III) triflate, a trivalent indium reagent, was shown to be a highly-efficient catalyst for the conversion of primary amides to the corresponding nitriles. The successful reactions required 5 mol% of indium(III) triflate, and toluene was proved to be the most suitable solvent. Various amides were subjected to this method, and each produced the corresponding nitriles in excellent yields n Dioxolane is used in the production of lithium triflate and lithium iodide based electrolyte solutions for primary (single use) lithium batteries and as a solvent for removing photomasking compounds in the production of printed circuit boards.

The triflate 8-1 was prepared in high yield by the counteranion replacement reaction developed by Umemoto and co-worker . The fluorinating power of triflate 8-1 was the same as that of the fluoride 6-1 , but its nonhygroscopic nature made it a useful fluorinating agent in terms of handling and storage triflate-related ligands such as ethyl sulfate and bistriflimide, the additional dicoordinate copper complexes RCuOSO 3Et (2), [RCu(THF)][Cu(NTf 2) 2] (3) and RCuNTf 2 (4) could be isolated. Spectroscopic indications corroborate more CuI than CuII character in all RCuX derivatives.
