A novel approach was developed for the stereoselective synthesis of trans-3,4-dialkyl-substituted aluminacyclopentanes from α-olefins, metallic magnesium, and EtAlCl2 in the presence of catalytic amounts of Cp2ZrCl2. The hydrolysis and deuterolysis products of the 3,4-dialkyl-substituted aluminacyclopentanes obtained are only in the trans configuration.
