“…Monovalent Ni + or dehydrated Ni 2+ were also proposed by Lallemand et al relying on a combination of CO-FTIR analyses and EPR spectroscopy. 434 An original 13 C-NMR study of propylene dimerization at low temperatures on NiO/SiO 2 concluded that propylene was complexing with Ni 2+ ions. 435 DFT studies by Brogaard and Olsbye 381 claim that the most plausible active sites on SSZ-24 zeolite were Ni 2+ active sites.…”

“…The oligomerization of light olefins is an attractive method for the production of a wide range of key intermediates for fuel, petro-, and fine chemistry. The rich and unique reactivity of nickel with unsaturated compounds has made this metal tremendously successful in olefin oligomerization, for both homogeneous and heterogeneous catalysis, and from academic and industrial points of view. Contrary to other well-known metals in oligomerization such as titanium and chromium, nickel is able to oligomerize not only ethylene but also propylene and butenes, two classically elusive alkenes as regards metal-catalyzed oligomerization. This versatility allows nickel-based catalytic systems to transform light olefins into specific high-value products.…”

“…Similarly, the corresponding Pd(II) complexes Pd1-Pd2 were synthesized by exposing the ligands L1-L2 to (COD)PdMeCl (Scheme 1) in dichloromethane at ambient temperature. The obtained Pd(II) complexes were verified by 1 H and 13 C NMR (Fig. S9-S12, ESI †), MALDI-TOF MS (Fig.…”

“…Nickel metal exhibits rich and unique reactivity in olefin oligomerization, and thus, this metal has been tremendously successful for homogeneous and heterogeneous catalysis in both academic and industrial fields. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Over the years, an impressive research effort has been conducted to rationally design ligands for increased control of ethylene oligomerization and its corresponding selectivities.…”

“…They are used for copolymerization with ethylene for the purpose of obtaining low-and high-density linear polyethylene and for the preparation of detergents and synthetic lubricants [12,14,41,48,54,61,62]. They can also be used in the production of surfactants, agents for enhanced oil recovery, corrosion inhibitors, high-performance lubricating oils, linear alkylbenzenes, oxo-synthesis alcohols, a-olefin sulfonates, oil additives, and as drilling fluids [1,3,6,28,35,51,59]. The worldwide growth rate of LAOs production between 1980 and 1990 amounted to 10-15 wt% per year.…”
