A convenient and efficient chiral CuFe2O4@SiO2-Mn(III) Ch.salen nanocatalyst has been developed for the C-N cross-coupling reactions of aryl halides/ phenylboronic acid with N-heterocyclic compounds in water and/or DMSO under mild conditions. The catalyst could be applied for the N-arylation of a variety of nitrogen-containing heterocycles with aryl chlorides, bromides, iodides and phenylboronic acid under mild conditions. Moderate to good yields were achieved for all substrates. The structure of catalyst was characterized using various techniques including FT-IR, FE-SEM, EDX, XRD, TEM and TGA. The catalyst can be simply recovered and reused for several times without significant loss of activity.

AbstractA formal ethylene alkylarylation reaction with aryl halides and alkyl oxalates enabled by synergistic photoredox/nickel catalysis is reported. This protocol takes advantage of borates as a traceless activation group, achieving the formal ethylene difunctionalized products via a catalytic three-component 1,2-alkylarylation of vinyl borate followed by a base-assisted deborylation process. The mild conditions allow for excellent functional groups compatibility and broad substrate scope.

A copper-catalyzed direct sulfoxidation reaction by C(sp3)–H bond activation has been developed. Starting from sample aromatic methyl thioethers with aryl halides, versatile biologically-active arylbenzylsulfoxide derivatives were efficiently synthesized in good to high yields under mild conditions. This new methodology provides an economical approach toward C(sp3)–C(sp2) bond formation.

We have demonstrated the first ligand free CuI-nanoparticle catalyzed N-arylation of amides/cyclic amides in an ethylene glycol/2-propanol solvent system under mild conditions. This is further extended for one pot synthesis of benzimidazole, and quinazolinone via intermolecular amidation followed by cyclization.
