A process for making a compound having a five membered ring fused to an aromatic ring is described. In the process a starting material comprising the aromatic ring and an allyl compound in which at least one allylic substituent is a leaving group are combined in a solvent and in the presence of a copper (II) salt of a superacid. The starting material may be made in situ by reacting an aromatic precursor with an allyl compound in the presence of the copper II salt.

A one‐pot synthesis of dihydroindenes from substitutedbenzenes and haloalkenes was developed. The reaction proceeded via a copper(II) triflate [Cu(OTf)2]‐catalyzed tandem Friedel–Crafts alkylation/cyclization process with high efficiency under relatively mild conditions.
