Physical Data: a crystal structure of a MAD–benzophenone complex has been reported.3 Solubility: sol CH2Cl2, toluene, hexane. Form Supplied in: commercially available from TCI (Tokyo Kasei, Ltd.) as a 0.4 M toluene solution; prepared from commercially available reagents and used in situ without further purification. Preparative Method: prepared by reaction of a 1–2 M hexane solution of Trimethylaluminum with 2 equiv of 2,6-di-tert-butyl-4-methylphenol in toluene or CH2Cl2 at rt for 1 h.1, 2 Handling, Storage, and Precautions: the dry solid and solutions are highly flammable and must be handled in the absence of oxygen and moisture. The solution should be used as prepared for best results. Use in a fume hood.
