Summary on Grant Application Form |
Supported catalysts have the potential to combine the selectivity of homogeneous catalysts with the ease of separation afforded by heterogeneous catalysts. This proposal involves the preparation of a new class of supported catalysts based on metal-organic frameworks. It has recently been demonstrated that dicarboxylate anions are able to bridge between metal dimers or tetramers to form porous and robust coordination networks. These metal-organic frameworks have been shown to be capable of absorbing gases such as H2, and have attracted considerable interest for gas storage. We intend to use phosphine-carboxylate ligands such as PPh2CH2CO2-, PPh2C6H4CO2-, PPh(C6H4C02-)2 and P(C6H4C02-)3 to prepare coordination network structures which also contain phosphine groups. Ligands with two or more carboxylate groups will form coordination networks with a hard metal like zinc(II) or copper(II). Ligands with only one carboxylate group will require a combination of two types of metal to coordinate to both the hard carboxylate groups and the soft phosphine groups. The inclusion of soft metal centres such as palladium, platinum, rhodium and iridium will be investigated, either pendant to the metal-organic framework in the case of di- and tricarboxylates, or as a fundamental part, in the case of the monocarboxylates. The network structures formed will be characterised crystallographically where possible. The activity of these new materials in a number of catalytic processes will be assessed, starting with simple hydrogenation reactions for which there is considerable precedence, then looking at new tandem processes involving a hydrogenation step.
