Oxygen NMR spectroscopy

Oxygen-17 NMR spectroscopy has an immense potential for structural analysis of cyclic sulfoxides and sulfones as well as for providing insight into the nature of bonding within these two functional groups . Indeed, in addition to data concerning the NMR chemical shifts for several cyclic sulfoxides and sulfones, NMR chemical shift differences between several diastereotopic sulfonyl oxygens in both cyclic and acyclic systems have been reported .

All facets of study have been greatly aided by the ease with which crystal structures may be obtained and by the availability of sensitive Fourier transform NMR spectrometers which allow nuclei such as l70, 51V, wNb, s5Mo, and, K3W to be used for structural studies. Oxygen-17 NMR spectroscopy has proved to be particularly useful because 170 chemical shifts are very sensitive to environment. As a result it is possible to distinguish between terminal and various kinds of bridging oxygen sites. The l70 spectrum of [W Oi, ]2 and its structure are shown in Fig. Ifi-IOa/1 We see...
