Abstract

A family of 4-substituted bis(imino)pyridines, 4-X- iPrPDI (4-X- iPrPDI = 2,6-(2,6- iPr 2-C 6H 3N=CMe) 2-4-X-C 5H 2N; X = CF 3, tBu, Bn, NMe 2), has been synthesized and the iron coordination chemistry studied. Sodium amalgam reduction of the iron dihalides (4-X- iPrPDI)FeX 2 (X = Cl, Br) in the presence of excess carbon monoxide furnished the corresponding iron dicarbonyl compounds (4-X- iPrPDI)Fe(CO) 2. Equilibrium mixtures of the four- and five-coordinate iron dinitrogen compounds (4-X- iPrPDI)FeN 2 and (4-X- iPrPDI)Fe(N 2) 2 were prepared by performing the sodium amalgam reduction of the iron dihalides under a dinitrogen atmosphere. Electrochemical and spectroscopic measurements were conducted on the free ligands and the iron derivatives to systematically evaluate the influence of each para pyridine substituent on the electronic structure of the compound.
