Abstract:
In the first chapter of the thesis the synthesis of indolylsulfanyl acetamide derivatives using thio-oxindoles has been reported. The properties of this reaction are, one-pot, without using catalysts, acetonitrile solvent and the raw material is available. This reaction has high yield and seperation products is done using column chromatography. Indole derivatives has various medicinal and biological properties and synthetic products in this project has indole ring, aldehyde and amide functional groups. In the second chapter of the thesis, a new magnetic nanocatalyst has been designed. The magnetic nanoparticles were coated with triazole ligand and then palladium (II) ion was loaded onto the support surface. Because of the economical and industrial importance of oxidation of alcohols, in this project we decided to use the nano-catalyst to convert various alcohols to aldehydes selectively. The features of this reaction are, using water as a solvent, molecular oxygen as a green oxidant, easy separation of the catalyst using an external magnet and reuse of the catalyst at least 5 times without losing its catalytic activity
