Summary on Grant Application Form |
|
Bidentate phosphines are among the most popular ligands used in platinum group catalysis, primarily because of their steric, electronic and geometric versatility. However, despite the immense number of novel diphosphines that are now available our understanding of how factors such as chelate ring size, conformational flexibility and even steric bulk influence catalyst activity and selectivity is rather limited. In this regard one of the most striking illustrations of the influence of the diphosphine on selectivity is the delicate balance of olefin alkoxycarbonylation versus CO-ethylene co-polymerisation. The alkoxycarbonylation of olefins is of immense importance for the synthesis of alkyl propionates whereas the alternating co-polymerisation of olefins with carbon monoxide generates polyketone, a revolutionary new wear-resistant engineering thermolplastic. This project aims to investigate the origin of olefin carboxylation selectivity by a combination of synthetic studies and complementary mechanistic investigations. This project will build on our recent discovery of a new class of co-polymerisation catalyst based on o-xylene bridge bis (phospholyl) ligands. The proposed research will enable us to systematically examine the influence of chelate ring size, steric bulk and phosphine basicity within a well-defined range of closely related phosphines. Ultimately, the ideas developed herein will be applied to olefin polymerisation catalysis.
