5. Photoredox-Catalysis and Bio-catalysis

The sustainable route for the construction of new C-X bonds using multiple activation modes to create a complex molecular framework. importantly, used of photo-redox and bio-catalysis avoids the use of multi-step synthesis and streamline the synthetic route

6. Transition metal catalyzed shuttle catalysis:

With the aid of shuttle catalysis, we want to introduce carbonyl, cyano, halides etc. without even using poisonous gases like CO, HCN etc. Thus, it provides a gas free approach to synthesize a number of useful organic entities using surrogates that finds application in the synthesis of naturally product derivatives and pharmaceutically relevant compounds.

7. Electrocatalysis and its application to organic synthesis:

Our main aim is to use 3d non-precious transition metals (Ni, Mn, Fe, Co, etc.) along with electrocatalysis to activate different distal C-H bonds. Employing this strategy, we are trying to decarboxylate various unactivated carboxylic acid in a very mild condition. Electricity will not only help us to activate the distal C-H bond it will also help to achieve the selectivity in very milder condition.

Electrochemical Oxidative C−H functionalization: A Metal-free Approach, Manuscript Submitted

Transition metal-catalyzed coupling is one of the most significant method for the development of new carbon-carbon, carbon-oxygen and carbon-nitrogen bonds. This simple and straightforward method can be applied in the synthesis of natural products, complex organic molecules and important pharmaceuticals. We are interested to develop transition metal as well as bio and photoredox-catalysis based protocols, which enable the alternative sustainable route for the synthesis of complex organic molecules with high efficiency and selectivity. In this direction application of highly abundant, readily available and non-precious Cobalt, Iron and manganese-based pincer complexes are best alternative to the widely used precious metal-catalysts, for application in sustainable organic transformations.
