A practical nickel-catalyzed reductive alkylation of amidophenyl bromides
摘要:
A modified Weix's reductive coupling for alkylation of amidoaryl bromides based on Ni(COD)(2) precatalyst and 2,2'-dipyridyl ligand was developed. This reaction is reliable for amidophenyl bromides and gives yields up to 87%, and is potentially useful in the synthesis of amidophenyl-containing molecules. (C) 2014 Elsevier Ltd.

Copolymer-Incarcerated Nickel Nanoparticles with <i>N</i>-Heterocyclic Carbene Precursors as Active Cross-Linking Agents for Corriu–Kumada–Tamao Reaction
We have developed heterogeneous polymer-incarcerated nickel nanoparticles (NPs), which catalyze cross-coupling reactions. The matrix structure of these catalysts incorporates both N-heterocyclic carbenes (NHCs) as ligands and Ni-NPs, thanks to a new design of cross-linking agents in polymer supports. These embedded NHCs were detected by field gradient swollen-resin magic angle spinning NMR analysis. They were successfully applied to Corriu-Kumada-Tamao reactions with a broad substrate scope including functional group tolerance, and the catalyst could be recovered and reused several times without loss of activity.
