Efficient synthesis of Bis-hydrazines using heterogeneous catalysis

Hydrazine derivatives are known as an organic compounds group containing C=N-N=C functional groups. This π-conjugated system enables electronic excitation in the visible and near ultraviolet 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 treatment of tuberculosis, Parkinson's disease and hypertension. Schiff bases form an outstanding class of ligands because of their unique properties, such as stability under different conditions, diversity of donor sites, flexibility of synthesis, and formation of ranges in various coordination geometries of 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 a theoretical and practical point of view, the synthesis of hydrazine derivatives is an important issue. In the present work, we have described a new, efficient and environment benign synthetic method for the formation of hydrazine derivatives via heterogeneous catalysis starting from ketones.
