The addition of pyridyl and quinolyl nitriles to the 4-lithium salt of 1-hydroxy-2.2.4.5.5-pentamethyl-3-imidazoline with a silyl protected OH group affords 4-aminovinyl substituted imidazoline derivatives 3, 6, 9,12, and 15 which can be converted into the corresponding nitroxide radicals 5, 8, 11, 14 and 17. The 4-amino-1-azadiene residues of these imidazoline nitroxides form a series of chelates of palladium (22-26, 29-32) and with ruthenium half sandwich complexes (33-36). Coordination of the pyridine or quinoline N atom has been observed in mononuclear (19-21) and trinuclear (27, 28) palladium complexes and the structure of 19 was determined by X-ray diffraction.
