Phototautomerization of \b-diketones

Abstract

The phototautomerization of Bz2CH2, BzCH2CO2Et, and p-(EtO2CCH2CO)2C6H4 was studied. The ability of these compounds to photogenerate singlet oxygen was proportional to the degree of photoketonization, and hence, whether these compounds could be used as photosensitizer or as photostabilizer depended on their easiness of forming ketone via phototautomerization.

Key words: HYDROCARBON WITH TWO PHENYLS P, PHOTOCHEMICAL REACTION, OXYGEN, ETHYL ACETATE, BENZENECARBOXYLIC ACID P, ISOMERIZATION REACTION, TAUTOMERISM, LIGHT STABILIZER, SINGLET, PHOTOSENSITIZER, BETA DIKETONES, PROPANEDIONE P
