Organometallic general pathway

Figure 9.1 General pathway to deposit a metal M from an organometallic complex by OMCVD. This example refers to an organometallic precursor, for which all of the ligands except X have been omitted for clarity.

Covalent (e.g., alkyl, hydride) and ionic (e.g., chloride) ligands count for one electron, and coordinative ligands (e.g., CO, Ph3P, R3N) for two electrons per coordination site. A mechanistic pathway in organometallic catalysis generally... 

These derivatives have not only provided new synthetic pathways but have shown improved thermal stability (as in the case of arsenic ylides) and a modified pattern of chemical reactivity. The donor properties of ylides 55, 24), and most of their synthetic applications 103), have been covered in other reviews and articles 3, 26) and are not duplicated here. The general organometallic chemistry of arsenic, antimony, and bismuth is the subject of the invaluable monograph by Doak and Freedman 11). The broad scope of phosphorus ylide and pentaorganophosphorane chemistry was covered in the leading multivolume series on organophosphorus chemistry edited by Kosolapoff and Maier 3, 21). Finally, the recent... 

The application of organometallic complexes and moieties in life science, in general, or in radiopharmacy, in particular, is very recent. Still, bioorganometal-lic chemistry is progressing very fast since it offers an attractive and challenging topic besides the pathway of using classical coordination compounds. Clearly, novelty is not a sufficient argument to work in a field however,...
