“…A trinuclear heterometallic complex, Cp 2 Zr(X′)( µ -H) 2 Al(X)( µ -H) 2 TiCp 2 (X, X′ = Cl, H, BH 4 ) ( 84 ) ( Scheme 45 ), was synthesized by the reaction of Cp 2 ZrCl 2 and ½ (Cp 2 TiCl) 2 with LiBH 4 and LiAlH 4 in toluene at 0 °C [ 102 , 103 , 104 ]. Complex 84 , upon heating to 40 °C, transformed into 85 , in which metal atoms were bound by hydride bridges, forming a six-membered ring, Zr 2 AlH 3 .…”

Dimers and oligomers of alkenes represent a category of compounds that are in great demand in diverse industrial sectors. Among the developing synthetic methods, the catalysis of alkene dimerization and oligomerization using transition metal salts and complexes is of undoubted interest for practical applications. This approach demonstrates substantial potential, offering not only elevated reaction rates but also precise control over the chemo-, regio-, and stereoselectivity of the reactions. In this review, we discuss the data on catalytic systems for alkene dimerization and oligomerization. Our focus lies in the analysis of how the activity and chemoselectivity of these catalytic systems are influenced by various factors, such as the nature of the transition metal, the ligand environment, the activator, and the substrate structure. Notably, this review particularly discusses reaction mechanisms, encompassing metal complex activation, structural and dynamic features, and the reactivity of hydride intermediates, which serve as potential catalytically active centers in alkene dimerization and oligomerization.
