Chelate [2-(iminoethyl)pyridine N-oxide]metal complexes - Synthesis and structural comparison with their chemically related 2-(iminoethyl)pyridine- derived systems

The N,O-chelate ligands 2-(iminoethyl)pyridine N-oxide (2a) and 2-(iminoethyl)-6-isopropylpyridine N-oxide (2b) were prepared by conventional synthetic routes, the latter involving a variant of the Reissert-Henze reaction. Treatment of 2a with FeCl2 resulted in a deoxygenation reaction of the ligand and formation of the salt (bis{2-(iminoethyl)-pyridine}FeCl] +[FeCl4]- (18a). In contrast, the reaction of 2a with PdCl2 or CoCl2 cleanly furnished the six-membered chelate [κN,O-2(iminoethyl)pyridine N-oxide]MCl2 complexes (19a, M = Pd) or (20a, M = Co), respectively, which were both characterised by X-ray diffraction. Treatment of 2b with [NiBr2 (dme)], followed by crystallisation from THF, gave the complex [κN,O-2b)NiBr2(THF)] (21b), which features a distorted trigonal-bipyramidal coordination geometry of the central metal atom. The reaction of 2a with [NiBr2(dme)] gave the structurally related complex [(κN,O-2a)NiBr2(κO-2a)] (21a). The N,O-chelate Pd complex 19a was shown to be an active catalyst for the Suzuki coupling reaction. The ligand systems 2a,b and their related 2-(iminoethyl)-pyridines 3a,b and a variety of metal complexes of ligands 3 were also prepared and characterised for comparison by X-ray diffraction.
