Phosphorus-31 NMR Spectroscopy
A Concise Introduction for the Synthetic Organic and Organometallic Chemist
Softcover, 132 Pages
First Edition, 2008
The book is intended for an audience already familiar with proton and carbon NMR and commencing research in phosphane chemistry (broadly defined).
It is the primary aim of this book to enable the reader to identify the main factors governing the phosphorus chemical shift values in the 31P-NMR spectrum and to make an educated guess as to where the phosphorus resonance(s) of a given target compound can be expected. It is not within the scope of this book to enable one to predict a phosphorus chemical shift precisely or even within a reasonable margin of error, with a few notable exceptions.
The further intent of this book is to assist the reader in determining important issues like bond order, p-bonding contributions from substituents, the existence or non-existence of metallacycles etc., in short, to make structural assignments without the aid of X-ray crystal structure determinations and to explain structural differences in solution and the solid state where appropriate.
"Phosphorus-31 NMR Spectroscopy" is a compact textbook. The reader must have a basic knowledge of NMR (proton and carbon), upon which foundation the specific properties of the phosphorus nucleus are explained. Since phosphorus occurs in a wide array of compounds, from elemental phosphorus to various substituted phosphanes, oxides, halogenides and metal complexes, one can go into great detail regarding the effect on the chemical shift, which the author succeeds in doing beautifully. The weight of the book is undoubtedly due to the clear and exact, easily readable introduction to the most wide-ranging phosphorus-containing compounds. Admittedly, this author describes very well the broad spectrum of structures and complexes, and the attendant influence on the chemical shift. It is the section on transition metal complexes that will delight inorganic and other chemists, those who wish to synthesize and use organometallic complexes and determine their structures.
It is a pity that no examples of spectra are included, and that no advanced technical possibilities are mentioned. Thus, no illustrations of P-P coupling, P-H coupling, or 1H-decoupling are to be found. The various types of coupling are explained clearly, however, and coupling constant values are mentioned in the text, but something is missing without a pictorial representation. Nevertheless, this shortcoming is outweighed by the abovementioned precise explanations of the various phosphorus compounds.
