SYNTHESIS AND TRANSFORMATIONS OF METALLOCYCLES. 5. REGIOSELECTIVE SYNTHESIS OF β-SUBSTITUTED ALUMOCYCLOPENTANES BY THE CYCLOMETALLATION OF α-OLEFINS USING Et3Al IN THE PRESENCE OF Cp2ZrCl2

Article abstract of DOI:10.1007/BF01184540

A new method has been proposed for the synthesis of N-, O-, and S-containing alumocyclopentanes by the reaction of Et3Al with functional α-olefins in the presence of catalytic amounts of Cp2ZrCl2.The alumocyclopentanes obtained may react with S8 to give β-substituted tetrahydrothiophenes.
