2. BACKGROUND Metallacycles of the transition metals were well-known and extensively
studied in the 1970s and 1980s8, 13, 14 and have been reviewed recently. 15, 16 …

Selective production of linear α-olefins is of significant commercial interest. Recently
discovered catalytic systems based on titanium, tantalum, and chromium show remarkable …

Interest in green chemistry and clean processes has grown so much in recent years that
topics such as fluorous biphasic catalysis, metal organic frameworks, and process …

Linear α-olefins, such as 1-hexene and 1-octene, are important comonomers in the
production of linear low-density polyethylene (LLDPE). The conventional method of …

Catalytic ethylene oligomerization represents a topic of considerable current academic and
industrial interest, in particular for the production of linear α-olefins in the C4− C10 range …

Linear alpha olefins such as 1-hexene are widely used in the chemical industry. Over the
past 15 years there has been considerable industrial interest in the selective trimerisation of …

Cr (III) complexes of tridentate SNS ligands have been prepared and evaluated as catalysts
for ethylene trimerization, with several giving very high activity and excellent selectivity …

A theoretical study of a mechanism for ethylene trimerization, catalyzed by Cr-pyrrolyl
complexes, is proposed and investigated with density functional theory methods. The …

Methylaluminoxane (MAO)-activated chromium (III) complexes of tridentate PNP and SNS
ligands of the form (R2PCH2CH2) 2NR '(R= alkyl, aryl; R '= H, Me, benzyl) and …

With greater market demand, interest in the selective production of linear α-olefins has been
increasing. This review discusses the principles underlying the evolution of the ligand …
