Ruthenium complexes of diphenylphosphino derivatives of carboxylic amides: Synthesis and characterization of bidentate P,N- and P,O-chelate ligands and their reactivity towards [RuCl2(PPh3)3]

The chelating properties of ambidentate phosphane ligands with carboxylic amide motif were studied in the coordination sphere of Ru(II). These ligands act as P,N- or P,O-chelators with formation of octahedral mono- and bis-chelate Ru complexes.
