Figure 3
Contextual compounds. Double adducts (7) and (8) were previously reported. In acid, aromatized adduct (9) was favored over double addition. Double adduct (10) is the closest reported kin of (3). Recently reported (11) supports the proposed mechanism. Hydroperoxide (12) is a likely intermediate to (3). Dianhydride (13) is commonly used for ligand synthesis.
