Novel Polymerization of α‐Olefins with the Catalyst System Nickel/Aminobis(imino)phosphorane

A new type of linking of α-olefins upon polymerization has been achieved by catalysis with nickel(0) complexes and [X2NP(NX)2], X = Me3Si. 2,ω-linking leads to polymers with methyl branches at well-defined intervals; products of type 1 are obtained from linear α-olefins.
