Visible Light Driven Oxidation of Alcohols and Amines Using Scalable and Reusable Heterogeneous Photoredox Catalysts Applications to the Synthesis of Biologically Active Molecules

Abstract

Academia and chemical industries are very keen to design and develop more efficient catalytic methods to prepare fine chemicals and advance synthetic organic methodologies by replacing homogeneous catalysts. In the perspective of limited natural resources on the Earth s crust and impact of huge chemical waste generation on environmental degradation, catalytic processes with high atom economy receive great attention instead of stoichiometric reagents based protocols. Though the traditional homogeneous catalysts are efficient than the heterogeneous counterparts, but the former is more energy intensive involving high cost towards separation of catalysts as well as trace metal impurities from the products. In this context, the catalysis research community has devoted much effort to develop heterogeneous catalysts such as zeolites, mesoporous solids, organic-inorganic hybrid materials, supported noble- and non-noble metal catalysts to circumvent the problems encountered under homogeneous catalytic systems newline
