Dinitrosyl iron complexes have been invoked as viable entities that contribute towards the biological action of nitric oxide (NO). Synthetic iron dinitrosyl compounds display a variety of properties including the ability to transfer molecular oxygen to phosphines or alkenes, and the ability to serve as catalysts for the dimerization of olefins. Thus, the development of advanced undergraduate laboratory experiments in this field is both timely and appropriate. We have developed a prototype undergraduate research project involving the preparation of a series of dinitrosyl iron complexes of the form Fe(NO)2L2 (L = phosphine donor ligand). Preparing and characterizing these types of derivatives will provide students with the opportunity to learn and utilize a number of advanced laboratory techniques including the manipulation of air sensitive compounds, infrared and NMR spectroscopy, electrochemistry and infrared fiber-optic spectroelectrochemistry. This work was supported in part by a United States Department of Education GAANN fellowship.
