Scheme 3.3 Synthesis of 1,2 diimines by H + -catalyzed or Al-assisted condensation of 1,2-diones
and aminoazoles.
acterization does not give very meaningful data, for example no informative NMR
spectra could be obtained since only very broad signals are observed. Fig. 3.2
shows the results of an X-ray single structure analysis of compound 37 .
