Tris(allyl)aluminum as its THF adduct, [Al(η1-C3H5)3(THF)] (1), reacted with pyridine either under substitution to give [Al(η1-C3H5)3(py)] (7) (py = pyridine) or under carbometalation to give N-metalated 2-allyldihydropyridine depending on the solvent. The substituent pattern of the pyridine substrate and the aluminum center’s electrophilicity in [Al(η1-C3H5)3(L)] (L = neutral ligand) influenced the
