p-Toluenesulfonyl chloride

What is the purpose of TsCl?

Tosyl chloride (TsCl) is usually used as an activating group for primary alcohols. Due to its relatively large volume and the lower reactivity of secondary and tertiary alcohols, it usually doesn’t come into them, being selective to primary alcohols in most of the cases.

What is Toso organic chemistry?

A toluenesulfonyl (shortened tosyl, abbreviated Ts or Tos) group, H3CC6H4SO2, is a univalent organic group that consists of a tolyl group, H3CC6H4, joined to a sulfonyl group, SO2, with the open valence on sulfur.

Why is pyridine used with TsCl?

Treatment of an alcohol with TsCl or MsCl, usually in the presence of a weak base such as pyridine, results in the sulfonate esters. (The purpose of pyridine is to mop up any HCl that is formed during the course of the reaction.)

How is sulfonyl chloride made?

Aromatic sulfonic acids and sulfonyl chlorides can be prepared by sulfonation of benzene derivatives with fuming sulfuric acid and chlorosulfonic acid, ClSO3H, respectively, while aliphatic sulfonic acids are prepared by vigorous oxidation of thiols or by reaction of amine sulfur trioxide complexes (e.g., Me3NSO3) with …

What are Tosylates?

Tosylates are good substrates for substitution reactions, reacting with nucleophiles in much the same way as alkyl halides. The advantage of this method is that the substitutions reactions are not under the strongly acidic conditions. Used mostly for 1o and 2o ROH (hence SN2 reactions).

What is difference between SN1 and SN2?

To understand the difference between SN1 and SN2, it is important to know their definitions first….

How does TsCl react with alcohol?

One example of this is the tosyl chloride(TsCl) reaction with an alcohol to form tosylate esters, commonly used synthons in organic chemistry. Tosyl chloride reaction with alcohol can occur intermolecularly or intramolecularly by associating the alcohol and tosyl electrophile through hydrogen bonding or coordination.
