Preparation of mesylates and tosylates (video) | Khan Academy
https://www.khanacademy.org/science/organic-chemistry/alcohols-ethers-epoxides-sulfides/reactions-alcohols-tutorial/v/preparation-of-mesylates-and-tosylates
WEBYou can make mesylates and tosylates from alcohols. And you might want to do this, because mesylates and tosylates are better leaving groups. So if we look at a general reaction to form a tosylate, you would start with an alcohol and you'd add tosyl chlorides and also pyridine, and you would form your tosylate over here on the right.
