Abstract
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.
