The recent advances in K2S2O8-mediated cyclization/coupling reactions via an oxidative transformation

Transition metal-free organic transformations using K2S2O8 is one of the most efficient methods for the formation of carbon–carbon/carbon–heteroatom bond in organic synthesis. K2S2O8-mediated transformations provide a cost-effective and green method for these type of transformations. In addition, these reaction methods are alternatives for many metal-mediated/catalyzed reactions. This article mainly describes the recent advances in K2S2O8-mediated cyclization/coupling reactions via oxidative transformation in organic synthesis in the last few years.
