A reusable polymer supported copper(I) complex for the C–N bond cross-coupling reaction

Copper catalysed Ullmann type chemistry: from mechanistic aspects to modern development

“…Moreover, the improved technologies in material chemistry have furnished the availability of nanostructures and nanoporous solids with very large surface areas, which lead to increased yields when compared to homogeneous catalysts. Several reports have appeared since the years 2006-2007 on cross-coupling reactions catalysed by silica- [258][259][260][261][262] and polymersupported 263 Cu species, dendrimeric ligand systems 264 and other heterogeneous copper sources, [265][266][267] and a discussion on some of these developments can be found in a recent review by Taillefer. 223 8.2.1 Copper nanoparticles.…”

Ligand-free copper(i) oxide nanoparticle-catalysed amination of aryl halides in ionic liquids

“…Both reactants are inexpensive, easy to handle and readily available. It is well known that Cu(I) in homogeneous 46,47 as well as in heterogeneous 48,49 catalysis promotes cross coupling reactions. In our case, we were pleased to see that iodobenzene couples smoothly even with ammonia in aqueous solution, in the presence of a ligand-free Cu 2 O nanocatalyst in n-Bu 4 POAc (Scheme 2).…”

Symmetrical Tertiary Amines: Applications and Synthetic Approaches

“…In 2011 Islam and co‐authors developed a polymer‐supported catalyst for the Ullmann‐type copper‐catalyzed protocol for the C‐N coupling. [ 344 ] This group used a polymer‐supported copper(I) catalyst to prepare triarylamines from anilines and aryl iodides (Scheme 132). The developed catalyst demonstrates the high efficiency in the synthesis of three symmetrical triarylamines.…”
