High-pressure cycloaddition reaction of 1,3-diphenylisobenzofuran with 6,6-diphenylfulvene gave exo- and endo-[4+2]π cycloadducts in 29 and 20% yields, respectively. The structures of exo- and endo-[4+2]π cycloadducts were elucidated by X-Ray crystallographic analysis, the latter of which included a benzene molecule.
