內容介紹：
Chemical and physical properties ofchemical entities in confined nanospace are expected to be different from theirbulk properties due to restricted rotational and vibrational motions. Suchrestricted motions along with other interaction/s may allow to stabilizeunusual conformations of compounds in confined space of molecular cavity.? Moreover, reactivity and reaction pathways inconfined space may become different from traditional bulk reactions leading tothe formation of unusual product/s. In this regard, chemists have been tryingto design artificial molecular vessels to perform chemical reactions in theirconfined nanospace. Design of 3D molecular architectures having hydrophobicconfined space including their use for catalytic organic transformations willbe discussed. The lecture will also focus on the interior decoration ofnanocages with urea moieties for new generation discrete heterogeneouscatalysts for Michael addition (Figure-1).1-7 It is also planned tofocus on our recent work on the use of confined space of discrete organic cagesfor the nucleation of tiny palladium nanoparticles and their successful use infacile transformation of aryl halides to corresponding cyanides.
