Dissertation/Thesis Abstract

Synthesis of Some Dinitrosyl Iron Complexes
by Khojandi, Niloufar, M.S., Southern Illinois University at Edwardsville, 2016, 55; 10164283
Abstract (Summary)

Bis(phosphino)amine containing {Fe(NO)2} 10 compounds have been synthesized by replacement of CO with amino phosphine groups in Fe(NO)2(CO)2 complexes. Bis(amino)-phosphine groups have been synthesized by aminolysis reactions between chlorodiphenylphosphine and aniline derivatives. In this study anilines with different substituents, which have a broad range of electron withdrawing and electron donating groups, have been used to determine the effect of the substituent on the nitrosyl ligand frequency in the IR spectra. 31P{1H} NMR has been used to confirm the formation of bis(phosphino)amines and IR spectroscopy has been used to follow the reaction and record the frequency shift of the nitrosyl ligand. ATR-IR also has been used to confirm the data, and also to compare solution and solid phases of dinitrosyl iron complexes (DNICs).

IR data show a small variation in the NO stretching frequency for the DNICs prepared with PNP ligands in solution. Those with more electron donating groups have lower νNOs and those with more electron-accepting groups have higher νNOs.
