| Abstract | 1,4-diazabicyclo[2.2.2]octane (DABCO) based ammonium salts immobilized on functionalized silica ascertained to be an effective heterogeneous catalyst for the cycloaddition reaction of carbon dioxide with epoxide under green reaction conditions without utilization of metals and any organic solvents. N-Benzyl DABCO bromide as a homogeneous analog of catalyst exhibited a lower catalytic activity than the supported catalyst. This is probably due to Si–OH groups on the silica surface which exhibited a synergistic effect with the halide anions. The effects of the grafted ammonium salts' structures and various reaction parameters on the catalytic activity were also investigated. The catalyst could be recovered in a facile way from the reaction mixture and also exhibited good reusability. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
