EXCEPTIONALLY BULKY LEWIS ACIDIC REAGENT, MAD

The key feature of MAD is the exceptional steric hinderance created by the two bulky 2,6-di-tert-butyl-4-methylphenoxy ligands which prevent s it from self-association and hence makes it feasible to exsit as a m onomer in solution, thereby inducing the inherent oxgenophilicity of a luminum.
