Abstract :

The adverse effect of the uses and generation of chemicals in the environment, humans, and the eco-system has urged the environment protecting agency to enforce rules and regulation that have made a renaissance in chemical research. Sustainability has become the hallmark of modern development in chemistry with increasing influence of green chemistry tools in chemistry research based organisation. The major aspect to implement green chemistry principles resides in the solvent use and the prime concern is touse green reaction media. Ionic Liquids (ILs) are hailed as future green solvents. However, combustibility and cytotoxicity of some ILs raise concern regarding their safe use as reaction medium. The fact that ILs can drastically alter the course of an organic reaction non-attainable with other reaction medium places ILs as a novel class of materials. The role of ILs in fostering sustainable chemistry development can be redefined through their non-solvent uses opening a new era of organo-catalysis. A molecular level understanding on how ILs influence organic reactions would promote their rational non-solvent applications has been the area of interest of this research group and is the context of present deliberation. The catalytic role of ILs has been revealed as ambiphilic dual activation by a relay of ?cooperative hydrogen bond and charge-charge interactions? in a variety of organic transformations. These offer in-depth analysis as to why all ILs are not equally effective for organo-catalytic uses and constitute a mass-spectrometry-based catalyst selection model by identification/ quantification of the supramolecular assemblies involved during the organo-catalysis by ILs.
