Photodimerizations of 3-Methoxy-1, 5-azulenequinone via Consecutive Pericyclic Reactions
3-Methoxy-1,5-azulenequinone gave dimers when irradiated with a high-pressure mercury lamp. The product distribution was dependent on the polarity of the solvent. In a polar solvent, a head-to-head dimer was predominant whereas a head-to-tail dimer was mainly formed in a nonpolar solvent.
