Ni(II) complex on a bispyridine-based porous organic polymer as a heterogeneous catalyst for ethylene oligomerization

A Ni(II) catalyst incorporated into a new porous organic polymer, Ni(II)-POP-1, is prepared via a click reaction followed by metalation with NiCl2. It shows good catalytic activity for liquid-phase ethylene dimerization in the presence of Et2AlCl as a co-catalyst, generating 1-butene.
