Abstract: | The mass spectrometric fragmentation of(S,S)-N,N′-bis1-(hydroxymethyl)alkyl]anthracene/naphthalene-1,8-dicarboxamides was investigated with the aid of mass-analyzed ion kinetic energy spectrometry and the elemental compositions of important fragment ions were determined by accurate mass measurement under electron impact ionization conditions. All the compounds could eliminate formaldehyde. The M-CH2O] ions could also eliminate imine, aziridine, aziridinone,2-amonoalkan-1-ol, water, and other fragments. Several cyclizations were observed under electron impact ionization. |
