Transition Metal Catalysis for Sustainable Organic Synthesis
Embedded Files
The synthesis of organic compounds sustainably is an essential requirement for many chemical industries. In this context, our group focused on the development of novel synthetic methods sustainably. The objective could be realized by considering the following aspects of the new synthetic method developments.
Earth-abundant 3d metal catalysts
Green and bio-mass derived solvents
Green energy resources
Effective utilization of green and renewable feedstocks
Efficient Recycling of Catalysts and Solvents
Adapting new techniques for organic synthesis
Effective utilization of computational methods to predict the reaction possibilities
C‒X (X = C, H, N, O, S) Bond Activations
Inventing novel transformations is the key to achieve sustainability in chemical synthesis. In this context, developing alternative methods to conventional multi-step functional group transformation is an ideal strategy to attain high-efficiency organic synthesis. Thus, our group focused on the functionalization of C-H bonds into various functional groups and complex natural scaffolds. This strategy significantly enhances the atom-economy of the overall transformations. Our focus also extends to develop new catalysts and reaction systems for C-C, C-O, C-S, C-N, and C-F activations.
Electro Organic Synthesis
Molecular synthesis in a sustainable manner is a prime area of research in both academia and industry. Thus, electrocatalysis uses electrons as a green reagent to produce useful products, significantly reducing the use of hazardous oxidizing or reducing reagents and ensuring high levels of sustainability. The recent emergence of metallaelectro-catalysis provides an opportunity to explore several oxidative transformations in the absence of toxic and expensive metal-based oxidants. Furthermore, several reported transformations follow a distinct mechanism under electrochemical conditions.
Electrochemical organic synthesis is a sustainable, eco-friendly, environmentally safe method for C-C and C-heteroatom bond formations via cross-couplings and C-H bond activation.
A controlled reaction pattern with switchable on-off electrochemical methods can be possible.
Electrocatalysis ensures high levels of atom-, step- redox-, and resource economy of the overall transformation.
Avoiding toxic oxidants and reductants is achievable; stoichiometric usage is completely reduced with the electrochemical approach.
Electrochemical synthesis empowers the improvement in terms of rate, yield, and time consumption
Enables effective scaling-up and increased turnover of catalyst to prevent overloading.
Photoredox Catalysis
Synthesis of organic compounds in an atom-economic and environment-friendly way is an essential and challenging task in industrial and academic research. Transition metal catalysis has advanced synthetic strategies over the last three decades through higher reactivity, regio- and stereoselectivities, excellent functional group tolerance, and improved atom efficiency. On the other hand, these transformations often require very high reaction temperature, hazardous reaction conditions, (super)stoichiometric oxidants or reductants, and demanding traditional and sensitive reagents. In recent years, photoredox catalysis has received significant attention in response to topical interest in renewable energy and green chemistry. This strategy allows accessing reactive intermediates under mild reaction conditions (often at room temperature) from less functionalized and/or abundant feedstocks. In this context, our group is interested in the merger of transition metal catalysis and photocatalysis, which could provide a versatile platform for developing new, highly enabling synthetic methodologies.
