Cycloaddition reaction of oxabenzonorbornadiene with 1,3-diphenylisobenzofuran gave two 1:1 adducts accompanied with 1,4-diphenylnaphthalene. The structural elucidations of these adducts were accomplished by spectral inspections. The product distributions are observed to be dependent on the reaction temperatures.
