A novel, acidic photo-oxidation product of benzene has been obtained, for which tentatively the structure: o-formyl-vpyrane (I) is proposed. Preparation: An aerated solution of benzene in water (5 1, pH = 5, 1 M phosphate buffer\*) was irradiated by a submerged Philips TUV 30 W low-pressure mercury

Photolysis of pyrophosphate and tripolyphosphate ions in aqueous solution is proposed to produce electron detachment with formation of pyrophosphate and tripolyphosphate radicals (with quantum yields Ο½0.1 at 266 nm), respectively. Formation of P 2 O 7 ΠΈ 3Οͺ is observed after photolysis of both polyph
