Laser flash photolysis study on hydrogen atom transfer of 2-(2-hydroxyphenyl)benzoxazole and 2-(2-hydroxyphenyl)benzothiazole in the triplet excited state
We have revealed that 2-(2-hydroxyphenyl)benzoxazole (HBO) and 2-(2-hydroxyphenyl)benzothiazole (HBT) underwent hydrogen atom transfer in the triplet excited state in benzene at room temperature and the equilibrium constants between the enol form and the cis-keto form were estimated.
