โœฆ Synopsis


The mass spectrometric behaviour of six Schiff bases derived from the condensation in acetonitrile or methanol of ferrocenecarboxaldehyde with polyamines H,N-R-NHz (R =-H,C-CHz-9-CHz-CHr, -HzC-CH,-, -HzC--CHrN[(CH2 ),,-CH3]-CHZ-CHz-, -(HzC)&,H8Nr(CHz)~) has been investigated by fast atom bombardment mass spectrometry and metastable ion studies. When oxygen and sulfur atoms are present in the ehaln, extensive fragmentation processes are observed, while the presence of nitrogen atoms leads to a more stable molecular species.

Four macrocyclic tetraimine Schiff bases containing oxamidic groups were synthesized by [2 + 2] condensation of N,N'-bis(2-aminoethyl)oxamide or N,N'-bis(2-amino-1,1-dimethylethyl)oxamide with 2,6-diformyl-4chlorophenol or 2,6-diformyl-4-methylphenol and characterized by elemental analyses and IR an
