Oligomerization nickel-catalyzed

As early as 1990, Chauvin and his co-workers from IFP published their first results on the biphasic, Ni-catalyzed dimerization of propene in ionic liquids of the [BMIM]Cl/AlCl3/AlEtCl2 type [4]. In the following years the nickel-catalyzed oligomerization of short-chain alkenes in chloroaluminate melts became one of the most intensively investigated applications of transition metal catalysts in ionic liquids to date.

Nickel-based catalyst systems constitute one of the important catalysts for olefin oligomerization, because nickel is the only metal that can control the mode of linking of olefins. The specific activity is high, and it is one of the less expensive transition elements. Because of these advantages, much research has gone into the study of nickel-catalyzed oligomerization [148-1811.
