Persistent four-coordinate iron-centered radical stabilized by π-donation

Dinuclear iron carbonyl complex , which contains an elongated unsupported Fe-Fe bond, was synthesized by the reaction between Fe (CO) and phosphinyl radical . Thermal Fe-Fe bond homolysis led to the generation of a four-coordinate carbonyl-based iron-centered radical, , which is stabilized by π-dona...

Zusammenfassung:Dinuclear iron carbonyl complex , which contains an elongated unsupported Fe-Fe bond, was synthesized by the reaction between Fe (CO) and phosphinyl radical . Thermal Fe-Fe bond homolysis led to the generation of a four-coordinate carbonyl-based iron-centered radical, , which is stabilized by π-donation. Complex exhibited high reactivity toward organic radicals to form diamagnetic five-coordinate Fe(ii) complexes.
