Recent Advances in Copper-Catalyzed Carbon Chalcogenides Cross- Coupling Reactions.

Cu-catalyzed carbon-heteroatom bond formation is a powerful tool in the field of organic synthesis. In the past two decades, numerous Cu-based catalytic systems are developed in both homogeneous and heterogeneous forms. Important developmentshave been reported on Cubased catalytic systems in the field of C-Chalcogenide cross-coupling in the last few decades. Where homogeneous Cu/L-based catalytic systems are found to perform reactions with high selectivity, heterogeneous supported-Cu and Cu-based nanoparticles are found to perform the reactions under sustainable conditions and high recyclability of catalytic systems. This present overview mainly focuses on the recent advances and applications in this fast-growing research field with an emphasis on copper-catalyzed cross-coupling generations of carbon-chalcogenide (S/Se/Te) bonds.
