Synthesis, Characterization and Catalytic Property Studies for Isoprene Polymerization of Iron Complexes Bearing Unionized Pyridine-Oxime Ligands.

ABSTRACT: Iron complexes of the types [Fe(HL)₂Cl₂] (Fe1: HL¹ = pyridine-2-aldoxime; Fe2: HL² = 6-methylpyridine-2-aldoxime; Fe3: HL³ = phenyl-2-pyridylketoxime; Fe4: HL⁴ = picolinaldehyde O-methyl oxime) were prepared and characterized by elemental analysis and IR spectroscopy. The crystal structure of Fe2, determined by single-crystal X-ray diffraction, featured a distorted octahedral coordination of the iron center binding with two ligands of HL². The X-ray structure and infrared spectral data indicated that pyridine-oxime ligands act as unionized bidentate ligand by coordinating with N_pyridine and N_oxime. The catalytic performance for isoprene polymerization, catal
