Hydroalumination of α-olefins by non-solvated polymeric aluminum hydride (AlH3)n occurs at 120-140°C. Mechanochemical activation accelerates this reaction. The addition of catalytic amounts of the prepared R3Al forms to the reaction system decreases the temperature of the process to 90-100°C. The greatest initiation effect is observed when ate-complexes of the MAlR4 type (M = Li, Na) are used: the reaction occurs with a higher rate already at 60-90°C affording R3Al free of admixtures of carbalumination products and dimers of α-olefins.
Continuous process for preparing aluminum alkyls and linear 1-olefins from internal olefins

Linear 1-olefins are continuously prepared from internal olevins by (i) continuously feeding internal olefin, isomerization catalyst and tri-lower alkyl aluminum to a reaction zone so as to cause the internal olefin to isomerize to 1-olefins which displace the lower alkyl groups to form a trialkyl aluminum compound in which at least one of the alkyl groups is a linear alkyl derived from the 1-olefin, (ii) continuously removing trialkylaluminum compound from the reaction zone and, thereafter, (iii) reacting the trialkyl aluminum compound with a 1-olefin so as to displace the linear alkyl from the trialkyl aluminum compound, thereby forming a linear 1-olefin product which is substantially free of internal olefins.
