Development of catalysts for hydrogenation reactions

Abstract

To synthesize the cyclohexyl derivatives the hydrogenation of substituted aromatic compounds holds significant importance due to their abundance and in nature Also, traditional techniques like aromatic substitutions, condensations, and cross-coupling reactions offer pathways to countless aromatic substrates. So, arene hydrogenation represents the most straightforward, retrosynthetically simple method to access a wide range of cyclic saturated compounds. Cyclohexyl derivatives have diverse applications across industries such as medicine, fuel, and polymers. The hydrogenation of aromatic compounds provides the way for the production of saturated cyclic compounds, opening up new synthetic pathways. This thesis focuses on the development of heterogeneous catalysts for the hydrogenation of aromatic compounds, aiming to convert them into corresponding hydrogenated forms and implement these findings in waste upcycling. This thesis comprises four chapters, structured as follows: The first chapter deals with the general introduction to aromatic compounds and their hydrogenated products. The second chapter includes the experimental procedures adopted for catalyst synthesis and the execution of various catalytic reactions. The third chapter includes a detailed discussion of the results obtained from various hydrogenation experiments. The final chapter presents the conclusion of the thesis, highlighting the major findings. The primary goal of this thesis is to develop an active and efficient heterogeneous catalyst that operates under environmentally benign conditions.
