Using a 250 ml balloon flask disposed in an argon atmosphere and provided with a magnetic stirrer rod, a solution of 0.493 g of triisobutylaluminium in 20 ml of pentane is introduced, and then a solution of 1.095 g of 2,6-di-t-butyl-4-methylphenol in 30 ml of pentane is introduced dropwise with agitation and at ambient temperature. After about 30 hours of reaction the pentane is evaporated under vacuum and analysis of the white solid remaining indicates that it is formed essentially by bis-(2,6-di-t-butyl-4-methylphenoxy)-isobutylaluminium. That compound is put back into solution in 5 ml of heptane.
