โœฆ Synopsis


A relation between 95M0 NMR chemical shifts, semi-empirical CNDO estimated p and d orbital electron population and oxygen transfer capacity for a number of dioxomolybdenum(VI) complexes containing the unit [MoWOz ] is discussed. The way in which the oxo ligand electronic structure could influence on its oxygen transfer capacity, i.e. intermolecular or intramoleculafly is analyzed. Compounds exhibiting negative chemical shift are associated with nucleophilic attack to the oxo ligand and intermolecular oxygen transfer, while those showing a positive chemical shift are associated with intramolecular oxygen transfer.

Poor correlations are normally observed between the chemical shifts of the various NMR-active nuclei in Mo carbonyl complexes of group 15 ligands as the group 15 atom substituents are varied. It is possible to observe good chemical shift correlations and to develop relationships between chemical shi
