New 3-imidazoline-1-oxyl radicals with pyridyl and quinolyl containing 4-(2-aminovinyl) substituents and palladium, platinum and ruthenium complexes of these 4-amino-1-aza-diene ligands

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.

Process for the preparation of imidazoline nitroxyl

A process is provided for the preparation of imidazoline derivatives such as imidazoline nitroxyls and 1-hydroxy imidazoline.

EFFECT OF THE CHEMICAL STRUCTURE OF NITROXYL RADICALS ON THEIR REACTIVITY IN THE REACTION WITH HYDRAZOBENZENE AND TETRANITROMETHANE

The reaction rate constants of reduction of stable radicals of different classes by hydrazobenzene in hexane at ca. 20 deg C, in the range of 0.4 - 5*103 M-1 sec-1, were determined; a single scale of the oxidative properties of stable nitroxyl radicals was constructed.The rate constants of oxidation of a series of nitroxyl radicals by tetranitromethane in aqueous medium at ca. 20 deg C, in the range of 0.06 - 10 M-1 sec-1, were determined.It was shown that the oxidative properties of the nitroxyl group decrease slightly with an increase in its reducing properties for nitroxyl radicals of the piperidine and imidazoline series in reactions with ascorbic acid and tetranitromethane in aqueous medium, respectively.

The Oxidative Properties of Nitroxy-radicals in Their Reactions with Sterically Hindered Hydroxylamines

A relative scale of the oxidative properties of cyclic nitroxy-radicals has been constructed and the influence of various structural factors on the oxidising capacity of the nitroxy-group in the radicals has been investigated.It is shown that the oxidative properties of the nitroxy-group in cyclic nitroxy-radicals become more pronounced with the increase in ring size.A relation has been established between the oxidative properties and the electron-accepting properties of functional groups separated from the nitroxy-group by two and more ?-bonds.
