  1. Reduction of alkenes to alkanes – hydrogenation most commonly used: Commonly used Metals: Pd, Rh, Ru, Ir, Commonly used Supports: Carbon (graphite), silica Stereochemistry: Why use a support to aid product seperation, how does the reaction work?

  2. Alkene oxidation reactions: Alkene oxidation reactions can give epoxides, diols, or even ketones from complete cleavage of the alkene. What is the structure of ozone? Look it up Why might these products be useful?

  3. Epoxidation of alkenes using peracids: This is one of the best mechanisms!

  4. Ozonolysis of alkenes cleaves the double bond:

  5. Alkene dihydroxylation: Note – OsO4 is expensive and very toxic. Better to use it catalytically (how would you do this?).

  6. The Wacker Oxidation: This is a commercial reaction used on a large scale in industry. The CuCl2 and O2 reoxidise the PdCl2 (Pd is expensive).
