Facile preparation of a Ni–imidazole compound with high activity for ethylene dimerization†
Abstract
A compound consisting of Ni and imidazole (Ni–imidazole) was synthesized in large quantities by a one-step co-precipitation method. The structure and stability of this Ni–imidazole were well studied by a series of characterization methods. The Ni–imidazole compound exhibited excellent catalytic properties for the dimerization of ethylene to 1-butene.
