1,3-Di-tert-butylisobenzofuran reacts with singlet oxygen with rate constant of 2.8E9 M^-1 sec^-1 to give stable endoperoxide 4.Thermolysis of the endoperoxide (4) in the presence of norbornene and naphthalene gave the corresponding epoxide and naphthols, respectively.Addition of Pd(OAc)2 improved the yield of naphthols considerably.
