The formation of amorphous Cu–MOF‐74 from crystalline Cu–MOF‐74 at 120 °C under strong alkali condition was reported for the first time, and it could be employed as an efficient heterogeneous catalyst for catalyzing cross‐coupling reactions between (hetero)aryl iodides/bromides and N ‐H heterocycles in high yields. The solid catalyst showed high catalytic activity with minimal copper leaching in reaction solution and lower copper contamination in N ‐arylated product than with other common copper/ligand systems, and it could be reused at least six times with no significant decrease in activity.
