The Thermolysis of Polyazapentadienes. Part 1. 1,5-Diaryl-1,2,5-triaza-derivatives
Flash vacuum pyrolysis of the title compounds at 600 deg C gives quinoxalines and arylamines, together with small quantities of nitriles, diarylamines, azobenzenes, and formamidines.The mechanism involves homolytic cleavage of the N-N bond to generate a conjugated iminyl radical, which can either cyclise to a quinoxaline, or fragment to simpler radicals which lead to the minor products by coupling reactions.

SYNTHESIS AND INVESTIGATION OF LIGANDS CONTAINING A HYDRAZONE GROUP V. SYNTHESIS OF IMINOHYDRAZONES OF UNSUBSTITUTED GLYOXAL
The synthesis of glyoxal iminohydrazones was realised by the succesive reaction of glyoxal with arylhydrazines and aromatic amines.On the basis of spectral data they were assigned a chelate structure with an intramolecular hydrogen bond.
