Triamino-s-triazine derivatives 3a, 4, and 5 have been prepared, and their cationic states have been analyzed electrochemically. At 298 K, 3a+ has a limited lifetime in CH2Cl2 solution. However, 4+ and 5+ are long-lived under such conditions, and quartet states of 43+ and 53+ are observed by ESR spectroscopy. Variable-temperature ESR analysis and NMR shift susceptibility measurements indicate that 53+ is a doublet ground state with a populated quartet state. |
