Title
Micellar Catalysis -Green and Efficient Approach for Selective Synthesis of Industrially Important Compounds.
Abstract: From a view point of global sustainability tremendous efforts is being made by the synthetic chemist to develop non hazardous energy efficient and environmentally benign routes for industrially important compounds. Use of water as solvent reaction medium is helpful in the practice to green approach and sustainability. Micellar catalysis is currently a rapidly expanding area of research. The use of surfactants micelle are increasingly being utilized as green reaction media in catalysis and offered numerous advantages over conventional catalytic systems (Homogeneous and Heterogeneous). Use of water as solvent solubilisation of organic compounds in water generation of huge interfacial area local concentration effect stabilization of charged intermediate/transition state reagent compatibility surface pH effect etc are the key attractive features of micellar system. Conventional base (NaOH KOH etc) catalyzed reactions are very common for the synthesis of industrial important compounds but problem of reagent incompatibility and non-reusability of inorganic base persists. This problem can be overcome using aqueous micellar solution as a reaction media. In addition reactions in aqueous micellar solution are faster and selective than biphasic reactions (in absence of surfactant) under ambient conditions.Bio-Sketch: Dr. Manu Vashishtha completed his PhD in chemistry from Department of Chemical Engg.Dharmsinh Desai University Nadiad Gujarat.His PhD work includes micellar catalysis for green and efficient synthesis of industrially important organic transformations. In addition his research interest also includes Photo-micellar catalysis for rapid waste degradation Biocatalysis using Lipase for synthesis of flavoring esters and Microemulsion technique for synthesis of metal oxide/doped nanoparticles.
