We have reported the synthesis of bicyclo[4.2.0]octa-3,7-drene-2,5-dlone L1 which is the valence isomer of 2,4,7-cyclooctatriene-1,4-dione 2. 2 As to yet unknown 3,5,7-cyclooctatriene-1,2-drone 3, there can be two valence isomers, 4

Recently Pappas and Pappas (1) have shown that acetylenes add photochemically to methoxy-p-benzoquinone to give derivatives of bicyclo[4.2.0]octa-3,7-diene-2,5-dione, The exact structure (Ia or Ib) of the phenylacetylene-methoxybenzoquinone adduct I was not determined. We have now found that this ad
