Copper immobilized at a covalent organic framework: an efficient and recyclable heterogeneous catalyst for the Chan–Lam coupling reaction of aryl boronic acids and amines

Abstract: A covalent organic framework immobilized Cu catalyst was prepared and applied for synthesis of N-arylated products by Chan–Lam coupling reaction of arylboronic acids with various amines.

“…The coupling of arylboronic acids with amines (Chan–Lam coupling) can be promoted by a catalytic amount of a copper‐impregnated imide COF (Figure e; Cu@PI‐COF). Cu@PI‐COF tolerates a wide range of substrates with yields up to 93 % and can be reused for eight cycles, thus offering a “green” way to N ‐arylated compounds …”

[211] Theb uilt-in pores in COFs offer an anospace to accommodate metal nanoparticles.Pd@CTF (Figure 49 f) promotes the reduction of awide range of nitroarenes to arylamines in nearly quantitative yield. [212] Similarly,C o@CTF with Co/ Co(OH) 2 nanoparticles catalyzes the reduction of arylnitrile and arylnitro compounds to arylamines in 87 %y ield.…”

“…Die Kupplung von Arylboronsäuren mit Aminen (Chan‐Lam‐Kupplung) kann durch eine katalytische Menge von kupferimprägniertem Imid‐COF (Abbildung e; Cu@PI‐COF) gefördert werden. Cu@PI‐COF toleriert einen weiten Bereich an Substraten mit Ausbeuten bis zu 93 %, kann für acht Zyklen wiederverwendet werden und ermöglicht einen nachhaltigen Zugang zu N‐arylierten Verbindungen …”
