  • Solubility of the catalysts in water is determined by their overall hydrophilic nature which may arise either as a consequence of the charge of the complex ion as a whole, or may be due to the good solubility of the ligands. Although transition metal complexes with small ionic ligands, such as halides, pseudohalides or simple carboxylates can be useful for specific reactions the possibility of the variation of such ligands is very limited. As in organometallic catalysis in general, phosphines play a leading role in aqueous organometallic catalysis (AOC), too.

  • 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.

  • Medicinal chemistry is a discipline at the intersection of chemistry, especially synthetic organic chemistry, and pharmacology and various other biological specialties, where they are involved with design, chemical synthesis and development for market of pharmaceutical agents (drugs). Compounds used in medical applications are most often organic compounds, which are often divided into the broad classes of small organic molecules and biologics, the latter of which are most often medicinal preparations of proteins. Inorganic and organometallic compounds are also useful as drugs.

  • Host-guest complexation relies on interactions of molecules through secondary chemical bonds. Such complexation can lead to formation of loose associations, as well as to that of very stable adducts. In formation of these addition compounds, important roles are played by hydrogen-bonding and hydrophobic interactions. In certain cases one of the reacting partners will wind up in a relatively enclosed space, embraced by the other reactant this is when the host-guest description is most appropriate.

  • 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.

  • 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 organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O. It is common to several classes of organic compounds, as part of many larger functional groups. The term carbonyl can also refer to carbon monoxide as a ligand in an inorganic or organometallic complex. Other organic carbonyls are urea and the carbamates, the derivatives of acyl chlorides chloroformates and phosgene, carbonate esters, thioesters, lactones, lactams, hydroxamates, and isocyanates.

  • 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. ...

  • Heterocyclic Chemistry represents a vast and important area of research which is of interest to a wide spectrum of chemists. This is amply documented by the fact that various journals, societies, and interest groups have sprung up entirely devoted to the pursuit of heterocyclic chemistry. Surprisingly though, there exists to our knowledge no single periodical review alerting the reader on an annual basis to important developments of the subject. We have now been able to persuade...
