The introductory chapter represents an overview of Visible-light-mediated CS bond formations. This includes a brief discussion about the visible-light mediated CS bond formation via difunctionalization of alkynes, CH functionalization, and radical cyclization reaction. Since most of the chapters leading to the formation of CS bonds under photocatalytic conditions so more focus given to the CS bond forming reactions.enVisible-Light-MediatedC-S bond formationDifunctionalizationRadical CyclizationThesis
