nitrogen atom on the other in these systems becomes more pronounced with a decrease in the difference of their formal hybridization. While 1,1-di-aromatic substitution leads to a formal sp 2 hybridization at one nitrogen atom, introduction of a π-bond in the form of a Schiff base or an acetylamide function at the second nitrogen atom leads to different hydrazine conformations and N–N bond lengths.
