A new method for the utilization of compounds of the type [Ru(bpy)2(CO)Cl]+ as a starting material for the synthesis of [Ru(N6)]2+ type compounds
摘要:
[Ru(R-bpy)(2)Cl-2] is an important starting material for the synthesis of [Ru(N-6)](2+) complexes. During the conventional synthesis procedure of [Ru(R-bpy)(2)Cl-2], yield loss of up to 50% occurs, due to the formation of the side product [Ru(R-bpy)(2)(CO)Cl](+). The CO ligand hinders further conversion to [Ru(N-6)](2+). Here we describe a simple and efficient removement of the CO ligand followed by a complexation of a third chelating ligand generating [Ru(N-6)](2+). Complete removal of the CO ligand and formation of an intermediate state is verified by ESI-MS spectrometry and IR spectroscopy. After complexation of the third chelating ligand bpy, pure [Ru(R-bpy)(3)](2+) was formed with complete conversion. Purity of [Ru(R-bpy)(3)](2+) was ensured by IR-, NMR-spectroscopy and MS spectrometry. (C) 2015 Elsevier Ltd. All rights reserved.

The complex [RuCl(CO)(bipy)2]Cl, a product of the long term reaction of RuCl3.3H2O with 2 mol of bipyridyl (bipy) in refluxing dimethylformamide, produces H2, CO, and CO2 on photolysis in water; under CO the photochemical water–gasshiftreaction is catalytic.
