CONSTITUTION: This hydroperoxide is obtained by reaction of 100 pts.wt. of a compound of the formula (P and Q are each H or an alkyl; n is 1-3; Ar is a n-valent aromatic hydrocarbon) with an oxygen-contg. gas (e.g. air) under atomospheric pressure at 50-130 deg.C using 0.00001-5wt.% of a catalyst, i.e. manganese dioxide or permanganate. By the above method, the objective compound can be obtained at high conversion rate without formation of byproducts such as formic acid and acetic acid while suppressing the decomposition of the compound formed.
