Photochemical formation and reactions of furans

  • Alexander Schönberg

Abstract

According to Schulte-Frohlinde [1] 1,1′,4,4′-tetrahydro-(2,2′-bi-naphthalene)-1,1′,4,4′-tetrone (1) rearranges to 5-hydroxydinaphtho[1,2-b: 2′,3′-d]furan-7,12-dione (2) on irradiation with light of wavelength 365 mμ. The rearrangement only takes place in hydroxylic solvents, e.g. methanol, ethanol, aqueous tetrahydrofuran, and acetic acid. In benzene, toluene, tetralin, carbon tetrachloride, and anhydrous tetrahydrofuran no photo-reaction could be observed. The transformation 1→2 can also be effected thermally.
