Web22 aug. 2024 ยท A series of iminopyridine complexes of Fe(II) and Co(II) complexes bearing fluorinated aryl substituents were synthesized for the polymerization of isoprene. The structures of complexes 3a, 2b and 3b were determined by X-ray diffraction analysis. Complex 3a contained two iminopyridine ligands coordinated to the iron metal center โฆ WebGenerally, the fluoride ion F โ, in polar protic solvents, is not a nucleophilic species. It is the smallest single anion with the largest negative charge, and therefore, it is a very strong โฆ
