Phosphorus-31 NMR Spectroscopy

This unique book enables the reader to identify the main factors governing the phosphorus chemical shift values in the 31 P-NMR spectrum and to make an educated guess as to where the phosphorus resonance(s) of a given target compound can be expected.

Nuclear Magnetic Resonance is a powerful tool, especially for the identification of 1 13 hitherto unknown organic compounds. H- and C-NMR spectroscopy is known and applied by virtually every synthetically working Organic Chemist. Con- quently, the factors governing the differences in chemical shift values, based on chemical environment, bonding, temperature, solvent, pH, etc. , are well understood, and specialty methods developed for almost every conceivable structural challenge. Proton and carbon NMR spectroscopy is part of most bachelors degree courses, with advanced methods integrated into masters degree and other graduate courses. In view of this universal knowledge about proton and carbon NMR spectr- copy within the chemical community, it is remarkable that heteronuclear NMR is still looked upon as something of a curiosity. Admittedly, most organic compounds contain only nitrogen, oxygen, and sulfur atoms, as well as the obligatory hydrogen and carbon atoms, elements that have an unfavourable isotope distribution when it comes to NMR spectroscopy. Each of these three elements has a dominant isotope: 14 16 32 16 32 N (99. 63% natural abundance), O (99. 76%), and S (95. 02%), with O, S, and 34 14 S (4. 21%) NMR silent. N has a nuclear moment I = 1 and a sizeable quadrupolar moment that makes the NMR signals usually very broad and dif cult to analyse.

Good and quick overview over the topic Written for the Synthetic Chemist keeping theoretical considerations to a minimum Particularly well suited for the identification and prediction of new compounds Explains the structure-spectra relationship Includes supplementary material: sn.pub/extras

Autorentext
Olaf Kühl ist Privatdozent an der Universität Greifswald. Seine Forschungsschwerpunkte sind die metallorganische und bioanorganische Chemie. Nach dem Chemiestudium in Tübingen fertigte er seine Diplomarbeit in Vancouver und Adelaide an und promovierte in Leipzig. Postdoc-Aufenthalte in Greifswald und Dresden gaben ihm die Möglichkeit zur Habilitation, die er durch einen Lehrauftrag in Chemnitz, einer Gastprofessur in Alabama und zuletzt in Greifwald abschloss. Dort wurde er 2009 zum Leiter der bioanorganischen Forschungsgruppe ernannt. Seine Passion für die Wissensvermittlung zeigt sich unter anderem in über 50 Veröffentlichungen, 2 Büchern und 8 Patenten sowie seiner Tätigkeit als Editor einer wissenschaftlichen Zeitschrift.
