摘要:

The GC/MS spectra of the methyl adduct of PBN as the aminoxyl and as the corresponding hydroxylamine are reported. Similar results are obtained with higher alkyl analogues. With excess alkyl Grignard the O-alkyl hydroxylamine ether (PBN double adduct) is obtained if the solution is exposed to O2in the presence of the alkyl spin adduct of PBN. A mechanism involving radical trapping by the alkyl spin adduct is proposed.
