# Electrophilic aromatic substitution reaction of dihydrofuran-2,5-dione with anisole

I am having trouble understanding the reaction of anisole with dihydrofuran-2,5-dione (succinic anhydride) in presence of $$\ce{AlCl3}$$ and acid works or how an electrophile is formed. I feel like the product should be something like $$\ce{C11H12O4}$$.

• This looks like a Friedel-Crafts acylation to me. Maybe it all becomes clear after visiting the Wikipedia page. Feb 11 '14 at 14:29

Do you remember the role of $\ce{AlCl3}$ in electrophilic aromatic substitutions? Where could it possible attack here?
