A General and Efficient Copper Catalyst for the Double Carbonylation Reaction
摘要:
The use of (NHC)CuI complex in combination with a N-heterocyclic carbene precursor as catalyst for the double carbonylation of aryl Iodides and secondary amines solves the problem of using the precious metal Pd and phosphine ligands. The new protocol requires a nonprecious metal catalyst and has greater generality than those previously reported.

The Pd(triNHC) complex was synthesized and used for the carbonylativecoupling of amine and aryliodide. The electron‐rich nature of palladium catalysts promoted the formation of α‐ketoamides with good yields and selectivity.
