Para-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 …

Tosylate Ester Formation. We can transform an alcohol group into a sulfonic ester using para-toluene sulfonyl chloride (Ts-Cl) or methanesulfonyl chloride (Ms-Cl), creating what is termed …

Mesylate and tosylate groups are excellent leaving groups in nucleophilic substitution reactions because the negative charge on the leaving group is stabilized by resonance.

Unlike alcohols, mesylates and tosylates are always reacted with a salt such as NaCl or NaBr and not the acids. The use of salts is to ensures the halogens are in a form of good nucleophiles …
