A one-pot stereoselective method was developed for the synthesis of trans-3,4-dialkyltetrahydrothiophenes from alpha-olefins, EtAlCl(2), metallic magnesium, and elementary sulfur (S-8) in the presence of catalytic amounts of Cp(2)ZrCl(2).

Novel ‘one-pot’ catalytic methods for the synthesis of cyclopentanols, tetrahydrothiophenes, silacyclopentanes and phospholanes are based on successive transformations of olefins and organoaluminium compounds (R2AlR′) in the presence of Cp2ZrCl2 catalyst. In situ generated aluminacyclopentanes serve as common intermediates in these processes.
