Characterization, of organometallic complexes

The P nucleus has a spin of 1/2 and is 100% abundant. Its receptivity, a measure of the sensitivity toward NMR analysis, is 0.0665, in comparison with 1 for protons and 0.000175 for Thus, P NMR spectroscopy is an important method for the characterization of organometallic complexes. This subject has been extensively reviewed. - ... 

ABSTRACT. The construction of the variable temperature electrochemical cryostat equipped with non-aqueous reference half-cell with liquid junction and its utilization for the characterization of organometallic complexes is reported. New tetracarbonylbis(olefine) tungsten(O) complexes of the formula trans-W(CO)have been synthetized (where L is... 

The third area is the synthesis and characterization of aryldiazenido complexes of transition metals. In 1964 King and Bisnette isolated the first metal complex with an aryldiazenido ligand. The interest of organometallic chemists was concentrated mainly on the isolation and characterization of stable aryldiazenido complexes and not on potential metastable intermediates involved in metal-catalyzed dediazonia-tions. The situation is different, however, for metal complexes with alkyl-diazenido ligands. Complexes with aryl- and alkyldiazenido ligands are the subject of Chapter 10 in the forthcoming second book (Zollinger, 1995).

The synthesis, characterization, and catalytic properties of materials obtained by the reaction of organometallic complexes of IIB, IVA, and VIA with metallic particles were studied extensively. Two types of materials may be obtained by... 

This review covers the synthesis, characterization, and reaction chemistry of organometallic complexes of Sc, Y and the lanthanides reported in the year... 

The SSNMR technique has also been applied to characterize polymorphic systems of organometallic complexes. In one early application Lockhart and Manders (1986) studied three polycrystalline methyltin(IV) compounds. They were able to isolate one of the pure polymorphic modifications and to determine the presence of other modifications by SSNMR techniques. 

In this chapter, we have considered just a few types of reactions of organometallic compounds, principally the replacement of CO by other ligands and the reactions involved in syntheses of carbene and carbyne complexes. Additional types of reactions will be discussed in Chapter 14. We conclude this chapter with two examples of how spectral data may be used in the characterization of organometallic compounds. Further examples can be found in the problems at the end of this chapter and in Chapter 14.
