η6-Arene complexes of Ni(ii), efficient catalysts for 1,3-butadiene and styrene polymerization†
Abstract
A simple procedure for the preparation of cationic arene complexes of Ni(II) of composition [Ni(η6-ArX)(η3-C3H5)]+[BAr′4]− (X = OH, H) is reported. These compounds are shown to behave as highly active
