Pyridinium p-toluenesulfonate CAS: 24057-28-1 it’s a mild and efficient catalyst for the tetrahydropyranylation of alcohols.

Usage of Pyridine p-toluenesulfonate CAS: 24057-28-1:

Pyridine p-toluene sulfonate (PPTS) CAS: 24057-28-1 is a mild, laboratory - ready acid catalyst widely used in organic synthesis.PPTS can be seen simply as a substitute for toluenesulfonic acid, and all reactions performed with toluenesulfonic acid can also be performed with PPTS.However, it has more advantages than toluenesulfonic acid in the use. For example, toluenesulfonic acid is generally in the form of a hydrated crystal, while PPTS is anhydrous.Toluenesulfonic acid has a strong acid, but the acid of PPTS has no obvious effect on many acid-sensitive functional groups.

The reaction catalyzed by Pyridine p-toluenesulfonate CAS: 24057-28-1 (PPTS) is usually characterized by simple and mild reaction conditions, and the dosage is generally less than 30% mole. The two most widely used reactions are the acetalization reaction of hydroxyl group and silicoetherification reaction of hydroxyl group, as well as the reverse reaction of these two reactions, so it is widely used in the protection and de-protection of hydroxyl group
