Synthese von Di- und Tri(o-phenylendiamin)-Liganden
The o-phenylenediamine ligand trisamine, TRIPACEN (4) and bisamine, DIPACEN (8) are obtained by Williamson coupling of the potassium salt of 2,3-dinitrophenole (1) to tris(3-chlorpropyl)amine (2) or benzylbis(3-chlorpropyl)amine (5), respectively, followed by reduction of the nitro functions with Sn/HCl or Pd(OH)2/H2.
