Nanoparticle synthesis using plant extracts is biologically safe, cost-effective, and environment-friendly, hence attracting many researchers owing to its advantages over chemical or physical methods. In the current study copper silver nanoparticles have been synthesized by biological methods (using fruit extract). The leftover fruits collected from vendors were used for study, such as guava (P...

Among the different reducing agents tributyltin hydride was found to be a powerful reducing agent for the denitration of a series of tertiary and secondary nitroesters. The organotin residues removed from the crude product using saturated potassium fluoride solution. The yield of the reactions was 62-98%.
