Procedure

To a solution of AlCl3 (133 mg; 1.0 mmol) in Bu2O (4.0 mL) was added phenylmagnesium bromide (1.2 mL, 3.1 mmol, 2.6 M in Et2O) at ambient temperature. After stirring at ambient temperature overnight, the product mixture was purged with a strong stream of nitrogen gas to evaporate the THF and Et2O. Bu2O (5.0 mL) was added to the residue and the mixture was stirred overnight, then filtered and the filtrate was purged with a strong stream of nitrogen gas to provide Ph3Al as a solid.
