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
