Synthesis and transformations of metallocycles 5. Regioselective synthesis of ?-substituted alumocyclopentanes by the cyclometallation of ?-olefins using Et3Al in the presence of Cp2ZrCl2
摘要:
A new method has been proposed for the synthesis of N-, O-, and S-containing alumocyclopentanes by the reaction of Et3Al with functional alpha-olefins in the presence of catalytic amounts of Cp2ZrCl2. The alumocyclopentanes obtained may react with S8 to give beta-substituted tetrahydrothiophenes.
