Introduction

Recent times have witnessed the robustness of visible-light-mediated transformations due to their mild nature and diverse mode of reactivity. These are generally operative via radical pathways under metal or metal-free conditions, enriching the chemistry to synthesize various molecular architectures.

Herein, I will discuss the breaking of C–S and C–F bonds for the generation of C-centred radicals and its application in C–C bond forming reactions using photoredox catalysis and visible light.

Indranil Chatterjee

Indranil Chatterjee obtained his B.Sc. from Calcutta University, India in 2006. Then, he moved to IIT Kharagpur for his M.Sc. studies. In 2008, he started his Ph.D. studies at the Westfälische Wilhelms-University Muenster, Germany. Under the guidance of Professor Armido Studer, he focused on catalytic asymmetric cycloaddition reactions. After finishing his Ph.D. studies in November 2011, he joined Professor Paolo Melchiorre at theICIQ, Tarragona, Spain, as a Postdoctoral fellow in March 2012. His area of research mainly focused on new organocatalytic cascade reactions. Afterwards, from 2014 to 2016, he started another postdoc position with Professor Martin Oestreich at the Technische Universität Berlin and concentrated his research on Lewis acid catalysis. Since December 2016, he is holding a position as Assistant Professor at the Indian Institute of Technology Ropar, India.

He is the responsible guest editor for the new thematic issue "C–H bond functionalization: recent discoveries and future directions" in the Beilstein Journal of Organic Chemistry.
