WebThe oxidation of alkenes, alkanes, and alcohols with H2O2 is catalyzed efficiently using an in situ prepared catalyst comprised of a MnII salt and pyridine-2-carboxylic acid (PCA) together with a ketone in a wide range of solvents. The mechanism by which these reactions proceed is elucidated, with a particular focus on the role played by each reaction component: i.e., … WebAlcohols to alkyl chlorides using SOCl2, PCl3, or PCl5 Note that these reactions proceed with inversion of stereochemistry. SOCl2 Alcohols to alkyl bromides Note that some courses teach that SOCl 2 gives retention and SOCl 2 plus base (e.g. pyridine) gives inversion. Check with your teacher! Alcohols to tosylates and mesylates ("sulfonate esters")
Why is pyridine used when making tosyl esters from alcohols?

WebThus, alcohols can be converted to tosylates and mesylates which is a very good leaving group. Most common reagents for this are mesyl chloride, abbreviated MsCl and tosyl chloride, abbreviated TsCl. Alcohols are converted to alkyl tosylates by treatment with p-toluenesulfonyl chloride (TsCl) in the presence of pyridine.
