摘要: Carbon, silicon, germanium, tin and lead-centered radicals were reacted with 3-nitropentan-2-one 3-nitropentan-2-ol inside the cavity of an electron paramagnetic resonance spectrometer. In all cases, selective addition to nitrogroup was observed detection corresponding oxynitroxide radicals. case carbonyl substrate, alkyl acyl nitroxides also detected because α-photocleavage. The oxynitroxides decayed a first order kinetics via fragmentation carbon–nitrogen bond (denitration). Unexpectedly, activation parameters fairly similar those previously reported for tert-butyl almost independent from presence or hydroxyl group on carbon adjacent one bearing nitrogroup.
