Bifunctional acyl-bis(1,2,4-triazole) functioned as a highly reactive and nontoxic, halogen-free monomer for polyester synthesis that did not require a metal catalyst. Isophthaloyl 1,2,4-triazole was prepared from the corresponding chloride and polymerized with 1,12-dodecanediol at 120 °C in the presence of 4-(N,N-dimethylamino)pyridine, resulting in polyester with high molecular weight (Mn = 48.3

A convenient method is disclosed for the synthesis of both 3-hydroxyisoquinolines and 2-hydroxy-1,4-naphthoquinones from β-ketoesters using a one-pot aryne acyl-alkylation/condensation procedure. When performed in conjunction with a one-step method for the synthesis of the β-ketoester substrates, this method provides a new route to these polyaromatic structures in only two steps from commercially available carboxylic acid starting materials. The utility of this approach is demonstrated in the synthesis of the atropisomeric P,N-ligand, QUINAP. The Royal Society of Chemistry 2009.
