内容記述 |
We examined decomposition reactions of a hypervalent iodine compound, 4-carboxy-2-iodosobenzoic acid (IBA-COOH), induced by monochromatic X-ray irradiations around the iodine K-edge energy region in a phosphate buffer. A decomposition product, 2-iodoterephthalic acid (ITPA), was identified by liquid chromatography-mass spectrometry for all experiments, indicating the I-O bond breakages were induced by the X-ray irradiations. The ITPA production to IBA-COOH decomposition ratio for the second iodine K-shell resonant excitation (33.22 keV irradiation) was higher than that for the first excitation (33.18 keV irradiation). Those findings suggest that the iodine K-shell resonant excitations can induce selective bond breakages of IBA-COOH, and therefore the IBA-COOH could be a promising protecting group of caged compounds activated by the X-ray irradiations. |
