Reaction of four equivalents of 4‐hydroxyquinolin‐2(1 H )‐ones with one equivalent of acenaphthoquinone in absolute ethanol, containing catalytic triethylamine, gave 3,3′,3″,3‴‐(1,2‐dihydroacenaphthylene)‐1,1,2,2‐tetrayl‐tetrakis(4‐hydroxyquinolin‐2(1 H )‐ones) in a good to excellent yields. The structures of the products were elucidated by 1 H NMR, 13 C NMR, NMR, IR, mass spectra, and elemental analyses.
