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.

In today`s industry, hydroformylation is the largest volume homogeneous catalytic process employing organometallic catalysts [1]. The simplest representation of this process (Scheme 4.1) is the reaction of a terminal alkene with CO and to afford linear and branched aldehydes. n-Butyraldehyde is produced for manufacturing 2-ethylhexanol used on large scale as an additive in plastics industry. Therefore the straight chain product of propene hydroformylation (linear aldehyde) is more valuable than iso-butyraldehyde, although the branched isomer, as well, has a smaller but constant market. ...

Hydrogenation is one of the most intensively studied fields of metal complex catalyzed homogeneous transformations. There are several reasons for such a strong interest in this reaction. First of all, there are numerous important compounds which can be produced through hydrogenation, such as pharmaceuticals, herbicides, flavors, fragrances, etc [1-3]. Activation of is involved in other important industrial processes, such as hydroformylation, therefore the mechanistic conclusions drawn from hydrogenation studies can be relevant in those fields, as well.
