RESEARCH INTEREST

Our Research research work mainly focused on the design of products and processes by which maximum utilization of all the products or processes are possible so that, more resource-efficient and inherently safer design of molecules, materials, products, and processes can be pursued in a wide range of contexts.

Mechanistic Organometallic Chemistry and Catalysis: In last 2-3 decades, most important carbon–carbon and carbon-heteroatom bond-forming methodologies have involved using transition metals to mediate the reactions in a controlled and selective way. Nevertheless, efficient, selective, and direct functionalization of hydrocarbons under mild conditions remains a most difficult challenge to chemists even today because it’s readily available from inexpensive petrochemical and natural gas feedstock and has been utilized as raw materials for the production of materials and energy for many decades. Among many attractive approaches utilizing transition metals to activate C-H bonds facilely, chelation-assisted protocols based on the coordinating ability of an organic moiety in a ligand have attracted great attention. In this context, the present proposal aims to design a ligand that includes at least two different types of chemical functionality with variable electron density, so that differential binding can be achieved giving rise to high degree of chemo selectivity. Concurrently, these functionalities may also influence the bonding/reactivity/selectivity of the other ligands bound to the metal to allow functional cooperativity and redox tunablity via synergistic interaction between the metal ions and ligand, which could exhibit unusual properties as catalyst with better reactivity and stability for various important organic transformations such as transfer hydrogenation, C-C, C-O, C-N, and C-S coupling reaction.

Synthesis and photocatalytic application of Smart Material: It is necessary, continually, to devise, develop and deploy new techniques of investigation to understand how and why certain molecules transform readily and others do not when they impinge upon an active site. This is why a detailed understanding of the atomic architecture of the catalytically active centre is important to improve existing catalysts or design superior new ones. To achieve the goal for green chemistry, clean technology and sustainability, there is now an exigent need to design and develop catalysts that can cope with and transform readily available reactants in an environmentally benign manner. Towards this, an easy, sustainable, scalable and environmentally benign chemical method will be designed and developed to utilize above mentioned synthesized homogeneous complexes or ligands towards the synthesis of heterogeneous smart material. The synthesized smart material will be applied to the photo catalytic degradation of various organic and inorganic species from aqueous or gas phase systems in environmental clean-up, drinking water treatment, industrial and health applications. Along with this the activity of these materials will be checked for photochemical splitting of water into hydrogen and oxygen and for catalytic application for various methodology developments by using oxidative pathway.
