Description of Visible Light Photocatalyzed Redox-Neutral Organic Reactions and Synthesis of Novel Metal-Organic Frameworks (PDF)

Visible Light Photocatalyzed Redox-Neutral Organic Reactions and Synthesis of Novel Metal-Organic Frameworks by Basudev Sahoo is a great book available in (PDF) download. Visible light-mediated photocatalysis has emerged as an environmental friendly elegant approach for streamlined organic synthesis. Recently, many conceptually novel and challenging advancements have been accomplished in this growing research area. The content of this thesis is about the developments of novel methodologies for synthesis of valuable organic compounds using visible light photocatalysis as toolbox and also synthesis of novel metal-organic frameworks (MOFs) as characteristic porous materials.

In initial phase of my Ph.D. work, a novel dual catalytic system combining gold with visible light photoredox catalysis has been developed for selective intra- and intermolecular heteroarylation of non-activated alkenes under mild reaction conditions (Scheme 1.1). In this work, the compatibility of gold catalysis with photoredox catalysis was demonstrated for the first time. Furthermore, this methodology benefits from mild reaction conditions and readily available light sources and avoids the use of strong external oxidants in contrast to previous methods.
