| Outline of Final Research Achievements |
The purpose of this research is to design highly active and stable new catalyst with multiple activation sites that possess potentiality to activate CO2 and can be applied for one pot multicomponent coupling reaction under milder reaction condition. In this context, we could synthesize heterogenous bifunctional SiO2 based catalyst through functionalization of cheap silica with imidazole-based ligand. The imidazolinium salt acted as ligand for metal and activator for substrate and CO2. With this bifunctional system, cyclic carbonates were prepared using propargyl alcohols under mild reaction condition. Our system provided green route for this reaction without any additive such as organic and inorganic bases.

| Academic Significance and Societal Importance of the Research Achievements |
The catalyst developed by this research made the synthesis of cyclic carbonates and carbamates possible by utilizing CO2 which is a “green” perspective to the synthesis of value added compounds with easy recovery and reusability of the novel catalyst for its applicability in chemical industry.
