Although early methods for the construction of such molecules involved transition metals, recent advances in the field have witnessed a myriad of elegant reports without the use of metal sources. The serendipitous discovery and observation of synthetic chemists have realized that there lies a great potential in exploiting the inherent reactivity of molecules in absence of transition metal. The key to the success of such coupling reactions is the use of a strong base, oxidant and a catalytic amount of N-donor ligands which contribute significantly. This review aims to highlight the recent progress in the field of transition-metal-free direct C–C and C–heteroatom bond forming reactions via the use of a strong base and (or) an oxidant.</p>1 aMehta, Vaibhav, P.1 aPunji, Benudhar  uhttps://library.ncl.res.in/content/recent-advances-transition-metal-free-direct-c%E2%80%93c-and-c%E2%80%93heteroatom-bond-forming-reactions
