Di- and tri-organotin(IV) carboxylates of the type R2SnL2 R = CH3, n-C4H9, n-C8H17] and R3SnL R = CH3, n-C4H9, C6H5, where L= oxygen donor ligand, have been synthesized and characterized by various analytical techniques such as elemental analysis, FT-IR, NMR (1H, 13C) and single crystal X-ray analysis. The synthesized complexes were screened for their catalytic activity in synthesis of biodiesel-an alternative fuel, and biological activities such as antibacterial, antifungal and cytotoxicity. The triorganotin(IV) complexes exhibited comparatively higher catalytic and biological activities...

This book contains synthesis and characterization of potentially bioactive carboxylate complexes with transition metals. They also interact with DNA via intercalative mode of interaction. They were also tested for antileishmanial and antifungal activities and possess good activity. In the light of their biological activity results it can be assumed that these compounds can be used as potential candidates for drug designing.

Biodiesel was synthesized from vegetable oils by base-catalyzed transesterification with methanol in the presence of NaOH. The optimization of experimental parameters was established to achieve the maximum yield of product. The physical and fuel properties of biodiesel like dynamic viscosity, kinematic viscosity, acid number, density, flash point, cetane number, cloud point and pour point were determined and found comparable to ASTM standards. Prepared biodiesel was chemically characterized by FT-IR, NMR (1H & 13C) and GC-MS to elucidate the identification, quantification and chemical...
