文摘

NU-1000-(bpy)Ni^II, a highly porous MOF material possessing well-defined (bpy)Ni^II moieties, was prepared through solvent-assisted ligand incorporation (SALI). Treatment with Et₂AlCl affords a single-site catalyst with excellent catalytic activity for ethylene dimerization (intrinsic activity for butenes that is up to an order of magnitude higher than the corresponding (bpy)NiCl₂ homogeneous analogue) and stability (can be reused at least three times). The high porosity of this catalyst results in outstanding levels of activity at ambient temperature in gas-phase ethylene dimerization reactions, both under batch and continuous flow conditions.
