I₂/TBHP Reagent System: A Modern Paradigm for Organic Transformations**

Abstract

Abstract Molecular iodine in combination with TBHP offers an advanced concept for organic synthesis and catalysis by improving the selectivity and sustainability of organic transformations. It leads to the development of metal free greener protocols under ambient conditions either as a catalytic duo or as a reagent system in combination with an additive. The advent of this indispensable tool led to formation of complex organic architectures empowering novel reaction pathways through C−H functionalization, cyclization, cycloaddition, rearrangement, sulfonylation/sulfenylation and oxidation reactions in organic synthesis.
