Notes:
In the photochemical decomposition of triazene R—N=N—NR1R2 in CH3CN solutions, where R was (3-HOOC—, di-HOOC—, 4-HOOC—, 4-CN—)phenyl and R1, R2 were —CH3, —CH2H5, —CH(CH3)2, —CH2CH2OH, the corresponding phenyl-substituted radicals were identified as 5,5-dimethyl-1-pyrroline N-oxide (DMPO) or (CH3)3CNO adducts. The reaction is described by a first-order kinetics with a half lifetime of 7 s. If R was di-3,5-CON3-C6H3—, a nitrogen-centred radical was found on radiation in the solid state as well as in CH3CN solution with DMPO as spin trap.
