Notes:
1,2-Diketones may serve as starting materials for various carbo- or heterocyclic organic compounds. Two different synthetic routes towards poly(arylene)s containing structural units derived from the 1,2-diketo building block are presented. The first route involves the generation of polymeric 1,2-diketones via aryl-aryl coupling, followed by polymer-analogous derivatisation. The second synthetic sequence includes formation of the 1,2-diketo derivatives on the stage of monomeric compounds and subsequent polycondensation of these monomers. In this manner, aromatic polymers possessing the quinoxaline, 1,2,4-triazine and tetraphenylcyclopentadienone subunits are available. The polymeric 1,2,4-triazines are particularly attractive because they offer the possibility of a thermal conversion into polymers containing the diphenylacetylene building block.
