CuMoO 4 Bimetallic Nanoparticles, An Efficient Catalyst for Room Temperature C−S Cross‐Coupling of Thiols and Haloarenes

Cu II catalyst is less efficient at room temperature for C−S cross‐coupling. C−S cross‐coupling by Cu II catalyst at room temperature is not reported; however, doping of copper with molybdenum metal has been realized here to be more efficient for C−S cross‐coupling in comparison to general Cu II catalyst. The doped catalyst CuMoO 4 nanoparticle is found to be more efficient than copper. The catalyst works under mild conditions without any ligand at room temperature and is recyclable and effective for a wide range of thiols and haloarenes (ArI, ArBr, ArF) from milligram to gram scale. The copper‐based bimetallic catalyst is developed and recognized for C−S cross‐coupling of haloarenes with alkyl and aryl thiols.
