| Details: | Concept of chemical reactions in confined molecular pockets is a Nature’s gifted idea. Enzymatic reactions are the best examples of chemical transformations in confined pocket surrounded by the enzyme molecules. Chemists have been trying to mimic such natural process by employing chemically designed molecular containers. Chemical reactions in confined nanospace have drawn special attention due to several advantages compared to bulk reactions like: entropic benefit, enhanced effective concentration, stabilization of transition state by the walls of the molecular vessels. Design of 3D molecular architectures having hydrophobic confined space including their use for catalytic organic transformations will be discussed (Figure-1).1-6 The lecture will also focus on the interior decoration of nanocages with urea moieties for new generation discrete heterogeneous catalysts for Michael addition. It is also planned to focus on our recent work on the use of confined space of discrete organic cages for the nucleation of tiny palladium nanoparticles and their successful use in facile transformation of aryl halides to corresponding cyanides. |
