Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 29046-78-4, is researched, SMILESS is COCCOC.Cl[Ni]Cl, Molecular C4H10Cl2NiO2Journal, Applied Organometallic Chemistry called Polynuclear (α-diimine) nickel(II) complex as catalyst for ethylene oligomerization, Author is Li, Dan; Ma, Fengmin; Guo, Lijun; Huang, Jin; Zhang, Yu; Li, Feng; Li, Cuiqin, the main research direction is ethylene oligomerization polynuclear diimine nickel complex catalyst synthesis.Computed Properties of C4H10Cl2NiO2.
Late transition metal catalysts with single or multiple active centers have great attention in the ethylene oligomerization application owing to their unique properties. A new polynuclear (α-diimine) nickel(II) complex (PS-Ni complex) bearing the conjugated poly(Schiff-base) ligand (PS-ligand) was synthesized. The structures and the composition of the PS-ligand and the PS-Ni complex were characterized by Fourier transform IR (FTIR) anal., X-ray diffraction (XRD), XPS, SEM, thermogravimetric (TG) anal., NMR (NMR) and gel permeation chromatog. (GPC). The PS-Ni complex was used as precatalyst in ethylene oligomerization combined with methylaluminoxane (MAO) and has good catalytic activity for ethylene oligomerization under mild conditions. Compared with the corresponding mononuclear (α-diimine) nickel(II) complex, the PS-Ni complex showed higher activity of 17.62 × 105 g/(mol Ni·h), and the main products were C4 and C6 olefins in cyclohexane when the dosage of precatalyst was 2μmol, the Al/Ni molar ratio was 500, the ethylene pressure was 0.5 MPa, the reaction time was 60 min, and the reaction temperature was 25°C. The main oligomers were α-olefins, and the selectivity was up to 98.68%, due to the more electron-deficient catalytic centers of the conjugated structure of poly(Schiff-base) ligand.
After consulting a lot of data, we found that this compound(29046-78-4)Computed Properties of C4H10Cl2NiO2 can be used in many types of reactions. And in most cases, this compound has more advantages.
