Isocyanates react with alkenes, e.g. ethylene and propene, in a C-C bond forming reaction on ligand-nickel(0) systems to yield azanickelacyclopentanones.These metallacycles have been characterized spectroscopically, and their reaction behaviour is discussed.The regioisomeric distribution of the C-C coupling reaction is reported for the reaction with propene.The azanickelacyclopentanones obtained from isocyanates and alkenes react further with ethylene to give ring expansion, whereopen β-elimination to unsaturated amides follows.
