Abstract :
Fumaric and maleic acid esters are functionalised with propargylamine. A subsequent Pd/Cu catalysedoxidative homo-coupling of two alkyne moieties yields the corresponding dimers. Hence, a model ofan unsaturated polyester chain is cross-linked in a well-defined, metal-mediated reaction in a very high yield.
