Description générale

Copperis a versatile and widely used metal with significant importance in variousfields, particularly in catalysis and material science. In material science,copper is used in various conductive materials due to its excellent electricaland thermal conductivity, ductility, and corrosion resistance. Additionally,copper is also extensively used as a catalyst in various chemical reactions dueto its ability to facilitate electron transfer and promote redox reactions. Itoften acts as a catalyst in various reactions which include reduction, cross-couplingreactions and “click" chemistry (such as copper-catalyzed azide-alkynecycloaddition reactions.

Application

  • Photoinduced Copper-Catalyzed Aminoalkylation of Amino-Pendant Olefins.: This study explores the use of copper catalysts in photoinduced aminoalkylation reactions, highlighting the efficiency and potential applications in organic synthesis (Zhang et al., 2023).
  • Synthesis of Azoxy Compounds: from Copper Compounds to Mesoporous Silica-Encaged Ultrasmall Copper Catalysts.: This research focuses on the development of copper-based catalysts for the synthesis of azoxy compounds, emphasizing their application in sustainable chemistry (Han et al., 2023).
  • Cu-catalyzed enantioselective allylic alkylation with organolithium reagents.: The paper presents a method for enantioselective allylic alkylation using copper catalysts, providing insights into asymmetric synthesis techniques (Hornillos et al., 2017).
