Monometallic and heterobimetallic azanickellacycles as ethylene polymerization catalysts.
The azanickellacyclic complex (1) produced by trimerization of an isocyanide on the nickel atom is found to be a new ethylene polymerization catalyst; catalytic activity is increased by incorporation of the second metal to a diimino moiety of 1 leading to formation of heterobimetallic complexes.
