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 CuII catalyst. The doped catalyst CuMoO4 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
disclosed new bimetallic BaMoO4 nanoparticles for the C–Scross-couplingreaction. The C–Scross-couplingreaction of alkyl/aryl thiols with haloarenes was accomplished with high yields. The reaction has good functional group tolerance and selectivity. This is an efficient protocol for synthesizing the building blocks of pharmaceuticals containing C–S bonds. The catalyst is recyclable. The unactivated

Disclosed is a mild, scalable, visible-light-promotedcross-couplingreaction between thiols and aryl halides for the construction of C-S bonds in the absence of both transition metal and photoredox catalysts. The scope of aryl halides and thiol partners includes over 60 examples and therefore provides an entry point into various aryl thioether building blocks of pharmaceutical interest. Furthermore

In one aspect, the invention provides a method of promoting a carbon-sulfur bond forming reaction. In certain embodiments, the reaction comprises cross-coupling of a(n) (hetero)aryl halide with a thiol to form the carbon-sulfur bond, wherein the method is promoted by light irradiation in the absence of a photocatalyst. In other embodiments, the cross-coupling reaction can be promoted through visible light irradiation, including sunlight.
