Isocynates react with styrene at ligand-nickel(0) systems by 1/1 C-C coupling giving azanickelcyclopentanones.The nickela five-membered rings obtained in this way are characterized spectroscopically, and their reaction modes are described.Depending on the ligands and special reaction conditions it is shown that with continuous, slow addition of the isocyanate to the solution of styrene and the Lig-Ni⁰ starting complex catalytic formation of cinnamanilide occurs.
