There is no doubt that ESCA studies will be very helpful in understanding the structure of organometallic compounds. This is for example demonstrated by the recent study of J0RGENSEN 1 . We feel, however, that before we can make much progress in photoelectron spectral studies of many compounds, we must first get a clear idea of the basic phenomena which occur during photoelectron ejection in so...

The different coordination modes in fullerene organometallic complexes are reviewed. The main modes are η2 and η5, but there are some interesting studies about the other four, all of them are revised in order to show which is the state of art of this kind of compounds with the respect of the hapticity.

Lithium cyclopentadienides are important reagents for the synthesis of organometallic compounds. In addition they feature an interesting manifold of structural variations in solution and in the crystal [1]. Variable temperature NMR spectroscopy has revealed markedly temperature dependent equilibria between monomeric lithium cyclopentadienides and their respective lithiocene salts [2]. A typical...

The two-step mechanochemical preparation of carbene-pyridine complexes of palladium and platinum is reported. The organometallic products, which represent a class of commercially available catalysts, are rapidly formed in excellent yield proving solvent-free synthesis to be a viable synthetic alternative even in the case of NHC-containing compounds.

In seeking new drugs for the treatment of the parasitic disease Leishmaniasis, an extensive range of organometallic antimony(v) dicarboxylates of the form [SbR3(O2CR')2] have been synthesised, characterised and evaluated. The organometallic moieties (R) in the complexes vary in being Ph, tolyl (o, m or p), or benzyl. The carboxylates are predominantly substituted benzoates with some compounds i...

Introduction Recently, /3-disulphones wrere synthesised in high yields from sulphonyl fluorides by interaction with alkylmagnesium bromides [1]. It is assumed that this reaction proceeds through the formation of a monosulphone which undergoes a-metallation followed by further reaction with the sulphonyl fluoride to produce /?-disulphone. Since aromatic sulphones cannot be metallated at the a-po...

Bioinorganic medicinal chemistry remains a hot field for research aimed at developing novel anti-cancer treatments. Discovery of metal complexes as potent antitumor chemotherapeutics such as cisplatin led to a significant shift of focus toward organometallic/ bioinorganic compounds containing transition metals and their chelates as novel scaffolds for drug discovery. In that way, transition met...
