Pyridinium 4-toluenesulfonate

CAS: 24057-28-1
Molecular Formula: C12H13NO3S
Molecular Weight: 251.3015
Product description:Is an application in organic synthesis is very broad, gentle, lab regular acid catalytic reagent. PPTS can simply as a substitute p-toluene sulfonic acid, p-toluene sulfonic acid finish all PPTS reaction can also be completed. Has more to it than toluene sulfonic acid on the use of the advantages, such as: p-toluene sulfonic acid generally exists in the form of a hydrate crystals and use, and PPTS is without water; Strong acid, p-toluene sulfonic acid and PPTS acid for many acid sensitive functional groups do not produce significant effect. PPTS catalytic reaction usually has the characteristics of simple and mild reaction conditions, the dosage general within 30% Moore. It applies the most two reaction is acetal reaction of hydroxyl silicon and hydroxyl etherification reaction, and the two reaction of the reverse reaction, in the protection of the hydroxyl and so to protect the reaction has been widely used [2]. Can use different reaction solvent, the PPTS catalytic hydroxyl of acetal and silicon etherification reaction.
