Versuchsvorschrift

In a 200-mL flask which had been previously purged with nitrogen, 97 mL of hexane which had been purified by distillation was charged, and 2.54 mL (10 mmoles) of triisobutylaluminum, manufactured by Tosoh Finechem Corporation was then added for dissolution. Subsequently, 0.58 mL (10 mmoles) of ethanol, manufactured by Aldrich was added. The flask was heated on an oil bath, and hexane was refluxed for 2 hours, thereby terminating the reaction. The reaction mixture was directly cooled to room temperature, thereby obtaining a 0.1 moles/L hexane solution of diisobutylaluminum ethoxide.
