A new stereoselective method is developed for the synthesis of 1-chloro-, 1-alkoxy-, and 1-N,N-dialkylaminoalumino-cyclopentanes from alpha-olefins, metallic magnesium, and aluminum halides (AlCl3, RO-AlCl2, R2N-AlCl2) in the presence of catalytic amounts of Cp2ZrCl2 (Cp = eta5-C5H5). The products from hydrolysis and deuterolysis of the Al-substituted 3,4-dialkylaluminocyclopentanes (ACP) have the threo configuration.
