Book Description
The pentafluorophenyl group has been studied using nuclear magnetic resonance. The spectra of several pentafluorophenyl derivatives of widely varied chemical types have been analysed. Correlations are found among the nmr variables. In particular the coupling constant between ortho and para fluorines was found to give a straight line relationship with the chemical shift of the para fluorine. This is termed the J[subscript 24] - [phi]p relationship. Another meta fluorine coupling, the coupling constant between the two ortho fluorines, also forms a straight line relationship with the chemical shift of the para fluorine. These two correlations appear to be dependent upon the [pi] donor-acceptor character of the substituent. This argument is then used to study the electronic interactions in selected series of organometallic and inorganic compounds. Interpretations of the bonding involved in these compounds are also given.

Fluorine-19 Nuclear Magnetic Resonance
Author: Harold G. Lee

Languages : en
Pages : 35
Book Description
A detailed investigation of the reaction of a series of pyridines with titanium tetrafluoride has been carried out with high-resolution fluorine-19 nuclear magnetic resonance spectroscopy. Instead of the formation of only simple diadducts a mixture of products is found in the solvent acetonitrile. The main species are TiF4 - 2D, TiF3 - 3D(+) and TiF5 - D( - ). An extensive series of TiF5 - d( - ) complex ions is studied by (19)F nmr. Linear correlations of the chemical shifts of the fluorines in TiF4 - 2D and TiF5 - D( - ) complexes are found with the pKa values of the substituted pyridines. Some complexes of TiF4 with bidentate ligands are reported as well as some products with sulfur containing ligands. Fluorine-19 nmr data are also given for some GeF4 - 2D adducts where D represents some substituted pyridine 1-oxides. Geometrical isomers were found with GeF4 - 2D compounds and both first and second order nmr spectra were measured. (Modified author abstract).
