Studies on the Catalysis by Lithium Perchlorate of Reactions of Aromatic Amines with Diethyl Azodicarboxylate and Naphtalen-2-ol with 4-phenyl-1,2,4-triazoline-3,5-dione

“…Monosubstituted hydrazines are also intermediates in the preparation of heterocyclic compounds such as pyrazoles [19], indazoles [20], imidazolinones [21], and cinnolines [22]. Moreover, 2-heteroaryl hydrazines [23] are interesting synthetic targets due to their efficiency as ligands for a variety of metal complexes.…”
