Abstract

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