摘要: 3,5,3″,5″-Tetra(tert-butyl)-p-terphenoquinone (12b) was synthesized and characterized by its spectroscopic X-ray structural data. The ground state of 12b is singlet with a strong contribution biradical structure. Paramagnetic derivative 12b, such as the semiquinone radical anion (12bτ) O-protonated form, phenoxy (18), were studied ESR ENDOR spectroscopy.
