- Abstract
Azimines. VII . Preparation by Oxidation of Triazanes A novel method for the preparation of certain azimines 4 by oxidation of 1,2,3-trisubstituted triazanes 3 is described. Treatment of 3-aryl-triazane-1,2-diesters 3a-3c with lead tetraacetate afforded the 3-aryl-azimine-1,2-diesters 4a-4c. The precursor triazanes 3a-3c were prepared by addition of p-substituted anilines to diisopropyl diazene-1,2-dicarboxylate 1b. A comparison of the spectral properties of the azimines 4 with those of the correspondingly substituted triazanes 3 reveals the unsaturated and dipolar nature of the azimines 4.
