Hi Julián,

I think it´s more common that iron cations form ´stable´ complexes with alkoxydes and acetates rather than ketones. Most likely, iron can coordinate weakly to ketones but I think the reactivity associated with this type of coordination is much less common than other types of reactivity related to iron and ketones (i.e. hydrogenation of ketones):

and

Also, you can take a look at the CCDC crystal database to check if there are existing iron-ketone complexes (I did a quick search but I only found iron complexes with alkoxydes and acetates).

Juan V. Alegre-Requena Thank you so much for your answer. Kind regards, Julián.

Hi. How about 1,3-diketone ?

Such as -----> Tris(acetylacetonato) iron(III)
