Help with prediction products of a reaction!

4-phenylbutanoyl chloride + AlCl3 --> ?

the molecular formula of the product is C10H10O, and I need to determine the product. I was thinking an acylium ion would form, and then the carbonyl carbon would form a bond with the ring to make a bicyclic compound. Is this correct? I am also not sure where it would bond on the ring (ortho/meta/para).

Thanks!

I'm not sure, but I do not think that a reaction would occur. ALCl3 usually acts as a catalyst, and would just form an ionic bond with the oxygen on the carbonyl of the compound; there isn't another reactant to form some other compound.
