Abstract A novel regio- and stereoselective method for synthesizingthreo-2,3-disubstituted 1,4-dialumobutanes from α-olefins and haloalanes (Et2AlCl, (Et2N)2AlCl, (EtO)2AlCl, Bu i 2 AlCl) with the participation of catalytic amounts of Cp2ZrCl2 or ZrCl4 in the presence of magnesium metal was developed. The products of hydrolysis and deuterolysis of the dialuminum compounds obtained have athreo-configuration. The selective transformations of 1,4-dialumobutanes totrans-3,4-disubstituted tetrahydrothiophenes,trans-1,2-disubstituted cyclobutanes, and disubstituted α,ω-dienes were found to be possible.
