Pyridazines. LXII. Tetrazolo-Azido Equilibria of Tetrazolo[1,5-b ]pyridazines
Tetrazolo[l,5-b]pyridazines exist in solution exclusively in the tetrazolo form. In solutions of strong acids an equilibrium of both forms, azido and tetrazolo, is established.

1,2‐Diazetidines − Structure, Synthesis, and Functionalization
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

A new family of phosphorescent Pt(II) complexes with pyrimidinedipyrrolide ligands, including a pyrazine analog, was designed and synthesized. Their emission properties can be finely tuned via ligand modification, revealing strong phosphorescence originating from intraligand charge transfer transitions.
