✦ Synopsis

We have already reported that an irradiation of pyridazine N-oxides and hydrocarbons in an inert solvent such as dichloromethane afforded hydroxyl compounds by the oxygen transfer reaction of the N-oxides.

In a previous paper2), we reported that irradiation of pyridazine N-oxides in benzene or toluene as solvent, resulted in the formation of the corresponding phenols, derived from the solvent, in 30-40s yield based on the N-oxides consumed.

## Abstract In a two step reaction, hexamethylbenzene consumes two molecules of singlet oxygen to form epidioxy hydroperoxide **3**. The first step involves a [4 + 2]‐cycloaddition, which is followed by an ene‐reaction. The structure of the intermediary endoperoxide **2** has been established spect
