Article abstract of DOI:10.1016/0022-328X(88)80488-1

Isocyanates react with propene at ligand-nickel(0) systems by 1/1 CC coupling to give two isomer azanickelcyclopentanones.The nickel five-membered rings thus obtained were characterized and their reaction modes are described.Depending on the ligand present and under special reaction conditions, with continuous, slow addition of the isocyanate to a solution of propene and the (lig)Ni⁰ starting complex, that there is catalytic formation of crotonic acid anilide.
