Summary on Grant Application Form |
|
The proposed grant application outlines how palladium(O) -catalysed carbonylation reactions can be applied to an unprecedented synthesis of (potentially liquid-crystalline) saccharins and to the preparation of several new types of poly(ar)amides. Palladium-catalysed carbonylations have a number of advantages: they proceed in high yield and are suitable for polycondensations; carbon monoxide is a cheap monomer; the catalyst system is easily varied; and they can be carried out in solvents of low toxicity, such as NMP. Telechelic diamines with flexible poly-THF or polyethylene glycol segments are well-known monomers for the production of polyurethane/urea elastomers. We propose to use these commercially available oligomers for the preparation of polyamides for which we anticipate similar elastic properties. Thermoplastic elastomers are processible as well as recyclable but, unlike in the case of the hitherto dominating polyurethanes, our route will avoid the need for highly toxic isocyanate monomers. In addition, suitable comonomers for carbonylation polymerisations will be designed from amino acids by simple modifications that readily introduce iodophenyl substituents, thus giving access to potentially biodegradable polymers with non-toxic degradation products.
