Aluminum(III) Chloride → Tris(4-methylphenyl)alumane

Participants

Reaction Steps

To a solution of 4-methylphenylmagnesium bromide (9 mL, 9 mmol, 1.0 M in THF) was added a solution of AlCl3 (6 mL, 3 mmol, 0.5 M in THF) at 0° C. The mixture was stirred at room temperature for 15 hours. The solution was removed from the solids by cannula and the solvent was evaporated under a strong stream of dry nitrogen gas. The residue was washed twice with n-hexane (10 mL each) and filtered in an enclosed system (Schlenk filtration) to avoid exposure of the moisture sensitive organometallic product to the atmosphere. The filtered solid was dried under reduced pressure affording the title product (0.81 g, 72%).
