Article abstract of DOI:10.1246/cl.1992.369

The electron spin resonance (ESR) of the quartet state of 1,3,5-tris(diphenylamino)benzene (TDAB) is reported.The orange-colored cationic radical is prepared by oxidation of TDAB with trifluoroacetic anhydride in a tetrabutylammonium tetrafluoroborate-CH2Cl2 solution.The ESR spectrum reveals that the cationic radical shows a typical quartet signal and that it is extremely stable at room temperature.
