Synthesis Of Bis-hydrazine Using Heterogeneous Catalysis

Résumé: Hydrazine derivatives are known as a group of organic compounds containing C=N-N=C functional groups. This π-conjugated system enables electronic excitation in the visible and nearultraviolet regions. This is of particular interest for many applications, such as corrosion inhibition dye-sensitized solar cells (DSSC), organogels, and fluorescent probes for analytical testing. In addition, many hydrazine derivatives show notable biological and therapeutic activities such as the treatment of tuberculosis, Parkinson’s disease, and hypertension. Schiff bases form a remarkable class of ligands because of their unique properties, such as stability under different conditions, diversity of donor sites, the flexibility of synthesis, and formation of ranges in various coordination geometries in a wide range of complexes. Their complexes have received widespread attention due to their wide range of applications, such as catalysis, electrochemistry, biological sciences, optics, guest chemistry, and molecular recognition. Therefore, from theoretical and practical points of view, the synthesis of hydrazine derivatives is an important issue. In the present study, we describe a new, efficient, and environmentally benign synthetic method for the formation of hydrazine derivatives with heterogeneous catalysis starting from ketones.
