Charge-transfer excitation of complexes of anhydrides with indene or 1,1-dimethylindene in polar solvents leads to cyclobutadimerization via radical cations; the same products are formed using pyrylium salts as photosensitizers, as well as from the thermal oxidation; with ferric chloride; these reactions are quenchable with efficient electron donors.
