The realm of aqueous organometallic catalysis incorporates many more reactions and catalysts than discussed in the preceeding chapters. However, these were not investigated in so much detail as, for instance, hydrogenation or hydroformylation; some of them are mentioned only here and there. An attempt is made to give a representative sample of these studies.

Catalytic oxidation of organic compounds is an extremely important field of chemistry, spanning the range from biological oxidations to large scale industrial production of commodity chemicals. However, many of these transformations can hardly be classified as organometallic reactions, since the catalysts (often simple metal salts) and the intermediates can be rather regarded as coordination complexes than organometallic compounds.

A personal look at the history of aqueous organometallic catalysis “Organometallic chemistry deals with moisture sensitive compounds therefore all manipulations should be carried out under strictly anhydrous conditions” – this was the rule of thumb ever since the preparation of the first organometallic compounds. Not as if there were no isolated examples of water-stable organometallics from the very beginning, in fact Zeise`s salt, was prepared as early as 1827. Nevertheless, it is true, that compounds having highly polarized M-C, M-H etc.
