Summary on Grant Application Form |
|
The formation of alkenes combining with it the formation of a carbon-carbon bond represents a fundamental bond construction in organic synthesis. Typically in the laboratory and industry this is performed with stoichiometric phosphoros or transition metal based reagents. Due to the stoichiometry this is expensive and wasteful. This proposal describes a new strategy that could generate a catalytic olefination using metal alkylidene/oxo chemistry. Olefin metathesis has long been catalysed by transition metal complexes while the corresponding carbonyl metathesis reaction remains stoichiometric. We wish to investigate the conversion of the by-product of a transition metal mediated carbonyl olefination reaction, a metal oxo species, to a metal alkylidene, by cycloaddition and the recycloaddition with a suitable ketene. We propose to do this by careful investigation and tuning of new metal oxo complexes on manganese, molybdenum and chromium. The characterisation of such a process would lay the foundation for new technology in organic synthesis.
