In this work, an oxo‐bridged bimetallic CuMoO4 catalyst for Csp2−Se cross‐coupling of diaryldiselenides with aryl‐halides is reported. The current discovery is noteworthy, as the catalyst is eco‐friendly, easily accessible, air‐stable, and recyclable. The methodology exhibits broad substrate scope and the catalytic system tolerates common functional groups. The protocol uses aryl iodide and bromides as electrophile instead of boronic acids. This is the first example of using an oxo‐ bridged copper based bimetallic catalyst for Csp2−Se cross‐coupling reactions in water. C−Cl bond remains intact during reaction. [ABSTRACT FROM AUTHOR]

We disclosed new bimetallic BaMoO4 nanoparticles for the C–S cross-coupling reaction. The C–S cross-coupling reaction 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 bromo- and 4-acetyl fluoro-arenes can well couple to afford thioethers in high yields. The reaction is believed to proceed by oxidative addition and reductive elimination. [ABSTRACT FROM AUTHOR]

Herein we disclosed inexpensive copper(II) bimetallic CuMoO4 nanoparticles for the C–N cross-coupling reaction of alkyl and aryl amines with haloarenes. The reaction proceeds under mild and ligand free conditions. The catalyst is recyclable and effective for a wide range of amines and haloarenes. Here, the efficiency of the Cu(II) catalyst is increased by doping molybdenum metal. The bimetallic nanoparticles are anticipated to proceed via normal oxidative addition and reductive eliminations.
