We have developed a simple and direct method for the synthesis of diaryl ether under mild reaction conditions using an oxygen bridged bimetallic CuMoO4 nanocatalyst. The catalyst tolerated a wide range of substrates with various functional groups. The catalyst is efficient and recyclable. This methodology allowed easy access to nitrofen derivatives (herbicides) from unactivated 2,4-dichlorophenol, which are important for agriculture and pharmaceuticals. [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.
