Synthesis of [RuII(η6-p-cymene)(PPh3)(L)Cl]PF6 complexes with carbohydrate-derived phosphites, imidazole or indazole co-ligands

RuII(arene) complexes of the general formula [RuII(η6-p-cymene)(PPh3)(L)Cl]PF6 with L = P- or N-donor systems have been synthesized and characterized. Carbohydrate-derived phosphites, imidazole or indazole have been chosen as co-ligands and different synthetic routes have been explored to obtain the compounds. The organometallics were characterized by elemental analysis, electrospray ionization mass spectroscopy, 1H, 13C{1H}, 31P{1H} and 2D NMR spectroscopic methods.
