    en.wikipedia.org/wiki/Pyridinium_p-toluenesulfonate

    In organic synthesis, PPTS is used as a weakly acidic catalyst, providing an organic soluble source of pyridinium (C 5 H 5 NH +) ions.For example, PPTS is used to deprotect silyl ethers or tetrahydropyranyl ethers when a substrate is unstable to stronger acid catalysts.

  3. Tosyl group - Wikipedia

    en.wikipedia.org/wiki/Tosyl_group

    The toluenesulfonate (or tosylate) group refers to the −O−SO 2 C 6 H 4 CH 3 (–OTs) group, with an additional oxygen attached to sulfur and open valence on an oxygen. [3] In a chemical name, the term tosylate may either refer to the salts containing the anion of p -toluenesulfonic acid, TsO − M + (e.g., sodium p-toluenesulfonate ), or it ...

    en.wikipedia.org/wiki/Sodium_p-toluenesulfonate

    Sodium p-toluenesulfonate is an organic compound with the formula CH 3 C 6 H 4 SO 3 Na. It is white, water-soluble solid. It is produced by the neutralization toluenesulfonic acid with sodium hydroxide. It is also a common product from the reactions of sodium-based reagents with toluenesulfonates. [1]

    en.wikipedia.org/wiki/P-Toluenesulfonic_acid

    p-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6] The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos.

  6. Sulfonate - Wikipedia

    Esters with the general formula R 1 SO 2 OR 2 are called sulfonic esters.Individual members of the category are named analogously to how ordinary carboxyl esters are named.For example, if the R 2 group is a methyl group and the R 1 group is a trifluoromethyl group, the resulting compound is methyl trifluoromethanesulfonate.

    en.wikipedia.org/wiki/4-Toluenesulfonyl_chloride

    4-Toluenesulfonyl chloride (p-toluenesulfonyl chloride, toluene-p-sulfonyl chloride) is an organic compound with the formula CH 3 C 6 H 4 SO 2 Cl. This white, malodorous solid is a reagent widely used in organic synthesis. [2] Abbreviated TsCl or TosCl, it is a derivative of toluene and contains a sulfonyl chloride (−SO 2 Cl) functional group.
