✦ Synopsis

Three benzoin ethers (methyl, ethyl, isopropyl) were photo&d at 77 K in glassy ethanol, i.e. in a homogeneous solid environment. Benz& benzaldehyde, benzoic acid, benzoates, desoxybenzoin and oxetanols were the products obtained. The last two (Nor&h type II) products were formed only after prolonged irradiation times. Since the degrees of benzoin ether photoconversion were low and almost independent of irradiation time, it is concluded that the formation and subsequent recombination of primary fragments are the main reactions.

Flash photolysis of ethereal solutions of sodium results in the almost complete disappearance of the orfgind absorption b.and at 15000 cm-I and in the formation of solvated electrons. After the flash an intermediate with an absorption maximum at 12000 cm-l is formed. This absorption is assigned to a
